Free EPSO AD5 Exam Flashcards

Part 1 (Language 1, 65 min of timed tests): Verbal Reasoning (20 MCQs / 35 min, pass 10/20), Numerical Reasoning (10 MCQs / 20 min), and Abstract Reasoning (10 MCQs / 10 min; combined Numerical + Abstract pass mark 10/20). Part 2 (Language 2, 110 min of timed tests, for Part 1 passers): EU Knowledge (30 MCQs / 40 min, pass 15/30), Digital Skills (40 MCQs / 30 min, pass 20/40, scored only if EU Knowledge >= 15/30), and the Free-Text Essay on EU Matters / EUFTE (40 min, scored 0–10, pass 5/10). The amended notice separates Part 1 and Part 2; follow the invitation for session scheduling. All Part 2 candidates take EUFTE, but only the selected preliminary-ranked group has it marked.

Numerical and Abstract Reasoning are strictly an eliminatory pass/fail hurdle (10/20 combined) and carry 0% weight in both rankings. The Preliminary Ranking weights Verbal Reasoning 40%, EU Knowledge 30%, and Digital Skills 30% to determine which top candidates (in principle up to 1.5x the 1,490 places sought, 2,235 in principle; the Selection Board may increase the marking limit in view of equal scores) have their EUFTE marked and eligibility checked. The Final Ranking weights Verbal Reasoning 35%, EU Knowledge 25%, Digital Skills 25%, and the EUFTE 15%. These are score-ranking weights, not proportions of MCQs or a cross-test content blueprint.

Candidates must choose two different languages from the 24 official EU languages: Language 1 at minimum CEFR C1 (thorough knowledge) and Language 2 at minimum CEFR B2 (satisfactory knowledge). L2 may be any of the other 23 official EU languages and is no longer restricted to English, French, or German. L1 is used for Verbal, Numerical, and Abstract Reasoning; L2 is used for EU Knowledge, Digital Skills, and the EUFTE written test.

Eligibility requires: (1) citizenship of an EU Member State with full citizen rights; (2) completed university degree of at least 3 years (for EPSO/AD/427/26, diploma award decided by 30 September 2026); (3) L1 at C1 and a different L2 at B2; and (4) compliance with military-service and character obligations. No professional experience is required. The notice’s language levels apply to each required language ability. The top 1,490 final-ranked candidates (plus ties for the last place) enter the alphabetical Reserve List, making them eligible for recruitment interviews by EU institutions, though inclusion does not guarantee a job offer.

The Treaty of Paris (signed 1951, in force 23 July 1952) created the European Coal and Steel Community (ECSC) among the 'Inner Six' (Belgium, France, West Germany, Italy, Luxembourg, Netherlands) with a supranational High Authority; uniquely, it had a 50-year sunset clause and expired on 23 July 2002. The Treaties of Rome (signed 25 March 1957, in force 1 January 1958) created the European Economic Community (EEC — establishing the Customs Union, Four Freedoms, and CAP) and Euratom, concluded for an unlimited duration.

The Single European Act (signed 1986, in force 1 July 1987) set the 31 December 1992 deadline to complete the Single Market and expanded Qualified Majority Voting (QMV) in the Council for internal market harmonisation (now Art. 114 TFEU). The Treaty of Maastricht (signed 7 February 1992, in force 1 November 1993) founded the EU with its three-pillar temple structure (European Communities, CFSP, JHA), launched Economic and Monetary Union (EMU) with the 3% deficit and 60% debt convergence criteria, created EU Citizenship (now Art. 20 TFEU), and introduced the co-decision legislative procedure.

Amsterdam (in force 1999) integrated the Schengen acquis into the EU framework and shifted asylum, visas, and civil justice into the supranational first pillar. Nice (in force 2003) re-weighted Council votes and reformed institutional caps ahead of the 2004 enlargement. Lisbon (signed 13 December 2007, in force 1 December 2009) abolished the three-pillar system, conferred single legal personality on the EU (Art. 47 TEU), amended the existing TEU and renamed the EC Treaty as the TFEU, gave the Charter of Fundamental Rights binding primary-law status (Art. 6(1) TEU), made the European Council a formal institution with a 2.5-year President, and introduced Art. 50 TEU withdrawal and the European Citizens' Initiative.

Under Art. 1 TEU and Art. 1 TFEU, the TEU (55 articles) and TFEU (358 articles) have the exact same legal value — neither is subordinate to the other. The TEU sets out foundational values (Art. 2), objectives (Art. 3), competence principles (Art. 5), the institutional framework (Arts. 13–19), Common Foreign and Security Policy (CFSP/CSDP), accession (Art. 49), and withdrawal (Art. 50). The TFEU details concrete competence categories (Arts. 2–6), the Internal Market Four Freedoms, competition, EMU, and the operational rules for legislative, budgetary, and judicial procedures.

Conferral (Art. 5(2) TEU): the EU can act only within the limits of competences conferred on it by the Treaties; non-conferred competences remain with the Member States. Subsidiarity (Art. 5(3) TEU): in areas of non-exclusive competence, the EU acts only if the objectives cannot be sufficiently achieved by Member States and can be better achieved at Union level. Proportionality (Art. 5(4) TEU): EU action must not exceed what is necessary to achieve Treaty objectives. Under Protocol No. 2, national parliaments have 8 weeks to issue reasoned opinions on subsidiarity ('Yellow Card' at at least one-third of allocated votes, reduced to one-quarter for proposals under Article 76 TFEU; 'Orange Card' at at least a simple majority of allocated votes under OLP).

Exclusive Competence (Art. 3 TFEU — Member States legislate only if empowered by the EU or to implement EU acts): (1) customs union; (2) competition rules necessary for the internal market; (3) monetary policy for eurozone Member States; (4) conservation of marine biological resources under the CFP; (5) common commercial (trade) policy; plus exclusive external competence under Art. 3(2). Shared Competence (Art. 4 TFEU — Member States act to the extent the EU has not exercised its competence): internal market, social policy (defined aspects), cohesion, agriculture/fisheries, environment, consumer protection, transport, trans-European networks, energy, AFSJ and defined public-health safety concerns. In research/space and development/humanitarian aid, EU action does not prevent Member State action (Arts. 4(3)–(4)). Supporting/Coordinating (Art. 6 TFEU — no EU harmonisation of national laws): human health, industry, culture, tourism, education/vocational training/youth/sport, civil protection and administrative cooperation.

Regulations: have general application, are binding in their entirety, and are directly applicable in all Member States without national transposition. Directives: are binding as to the result to be achieved upon each Member State to which they are addressed, but leave national authorities the choice of form and methods (require transposition by a deadline; after the transposition deadline, unconditional and sufficiently precise provisions can have vertical direct effect against the state; a directive does not of itself impose obligations on a private party in a horizontal dispute). Decisions: are binding in their entirety (on specific addressees when specified). Recommendations and Opinions: have no binding legal force.

The 7 EU Institutions (Art. 13(1) TEU) are: (1) European Parliament, (2) European Council, (3) Council of the European Union (the Council), (4) European Commission, (5) Court of Justice of the European Union (CJEU), (6) European Central Bank (ECB), and (7) European Court of Auditors (ECA). Under Art. 13(4) TEU, the Parliament, Council, and Commission are assisted by two Advisory Bodies: the European Economic and Social Committee (EESC) and the European Committee of the Regions (CoR), each capped at 350 members appointed for 5-year terms.

The Commission (1 Commissioner per Member State = 27 members serving a 5-year term) promotes the general interest of the Union: it holds the near-monopoly on legislative initiative (Art. 17(2) TEU), acts as 'Guardian of the Treaties' via infringement actions (Art. 258 TFEU), executes the budget (Art. 317 TFEU), adopts delegated and implementing acts, and represents the EU externally (except in CFSP and other Treaty exceptions). Appointment: the European Council proposes a President-designate by QMV (taking EP elections into account); the EP elects the President by a majority of its component members; the Council and President-elect adopt the list of Commissioners-designate; after EP committee hearings, the EP votes consent to the whole College (including the HR/VP); the European Council formally appoints the Commission by QMV.

The Council consists of one ministerial representative from each of the 27 Member States authorised to commit their government, meeting in 10 thematic configurations (e.g., General Affairs, Foreign Affairs, ECOFIN, Justice and Home Affairs) depending on the policy topic, prepared by COREPER I (deputy permanent representatives: technical/sectoral files) and COREPER II (ambassadors: political, economic, foreign/JHA files). Nine configurations are chaired by a 6-month rotating national Presidency operating in 18-month 'Trios'. The sole exception is the Foreign Affairs Council (FAC), normally chaired by the High Representative of the Union for Foreign Affairs and Security Policy (HR/VP, Art. 18(3) TEU). When the FAC discusses common commercial policy, the rotating presidency chairs the meeting instead.

With all 27 states participating, standard QMV (when acting on a proposal from the Commission or HR/VP) requires a Double Majority: (1) at least 55% of the Member States (at least 15 out of 27 states), AND (2) Member States representing at least 65% of the total EU population. To block through the population threshold, a minority needs at least 4 Member States representing more than 35% of the EU population (so 3 large states with >35% population cannot block alone). Reinforced QMV (when the Council does NOT act on a Commission or HR/VP proposal) requires at least 72% of Member States (at least 20 out of 27) representing at least 65% of the EU population. A proposal also fails if it lacks the required number of supporting states; the four-state/population rule is not the only way a proposal can fail. Article 238(3) adjusts thresholds when not all states participate.

Under Art. 14(2) TEU, the European Parliament is capped at 750 MEPs plus the President (751 maximum); for the 2024–2029 term, the seat count is fixed at 720 MEPs. Seats are allocated by degressive proportionality: minimum 6 seats per Member State (Malta, Luxembourg, Cyprus) and maximum 96 seats (Germany), where each MEP from a more populous state represents more citizens than an MEP from a smaller state. Seating is organized by political affiliation rather than nationality; some MEPs are non-attached. Forming a political group requires at least 23 MEPs elected from at least one-quarter of the Member States (at least 7 of 27 states).

Under Parliament’s Rule 131, a motion of censure normally needs signatures from at least one-tenth of its component members (72 of 720). If another censure motion was voted on in the preceding two months, the threshold rises to one-fifth (144). The motion must state reasons. Debate begins no earlier than 24 hours after receipt is announced; a roll-call vote follows no earlier than 48 hours after the debate begins, subject also to Article 234 TFEU. Adoption needs two-thirds of votes cast and a majority of component members (361 of 720). If adopted, the Commission resigns collectively and the High Representative resigns from Commission duties.

The European Council comprises the Heads of State or Government of the 27 Member States, its President (elected by QMV for a 2.5-year term renewable once; may not hold a national office), and the President of the European Commission (the HR/VP takes part in its work). It defines the EU's general political directions and priorities but exercises NO legislative functions (Art. 15(1) TEU). It decides by consensus unless the Treaties specify unanimity, QMV, or simple majority (its President and the Commission President do not vote). By contrast, the Council of the EU is the ministerial co-legislator (Art. 16 TEU), and the Council of Europe is a separate non-EU 46-state international organisation in Strasbourg (European Convention on Human Rights / ECtHR).

The CJEU consists of two courts: (1) the Court of Justice (1 judge per Member State = 27 judges, assisted by 11 Advocates General who present impartial, non-binding reasoned opinions in open court) and (2) the General Court (2 judges per Member State = 54 judges, hearing direct actions by natural/legal persons, competition, state aid, IP, and since October 2024 transferred preliminary ruling areas such as VAT, customs, excise, ETS, and passenger compensation). Judges and Advocates General are appointed by common accord of Member State governments for renewable 6-year terms after suitability vetting by the independent seven-member Article 255 TFEU panel.

Preliminary Rulings (Art. 267): lower national courts may refer EU law interpretation/validity questions; courts of last instance MUST refer unless a CILFIT exception applies (irrelevance, acte eclaire, or acte clair), and under Foto-Frost only the CJEU can declare an EU act invalid. Annulment (Art. 263): brought within 2 months of publication, notification or knowledge, as applicable, to review legality of binding EU acts; Member States, EP, Council, and Commission are privileged applicants (unconditional standing), ECB/ECA/CoR are semi-privileged (protect own prerogatives), and individuals/companies may challenge acts addressed to them, or must show direct and individual concern (Plaumann test) or challenge a regulatory act of direct concern not entailing implementing measures. Infringement (Arts. 258–260): Commission issues a letter of formal notice -> reasoned opinion -> CJEU referral, with lump sum and/or daily penalty payments under Art. 260.

Seated in Frankfurt, the ECB's primary objective under Art. 127(1) TFEU is to maintain price stability (operationalised as a symmetric 2% inflation target over the medium term). Its three decision-making bodies are: (1) Executive Board: President, Vice-President, and 4 other members appointed by the European Council by QMV for a strictly non-renewable 8-year term (implements monetary policy and manages day-to-day business); (2) Governing Council: the 6 Executive Board members plus the governors of the national central banks (NCBs) of the eurozone Member States (the main policy body setting eurozone interest rates); and (3) General Council: the President, Vice-President, and the governors of the NCBs of all 27 EU Member States.

Seated in Luxembourg, the ECA consists of 1 member from each Member State (27 members), appointed by the Council by QMV after consulting the European Parliament for a renewable 6-year term. The ECA examines the accounts of all revenue and expenditure of the Union and its bodies to verify that financial management has been sound, and provides the Parliament and Council with an annual Statement of Assurance (DAS) certifying the reliability of the accounts and the legality and regularity of underlying transactions. The ECA has no judicial powers; suspected fraud against the EU budget is referred to OLAF or the European Public Prosecutor's Office (EPPO).

Normally initiated by a Commission proposal (Treaty exceptions exist), OLP makes the European Parliament (EP) and Council co-equal legislators: (1) First Reading (no time limit): EP adopts its position by simple majority; if the Council approves (by QMV, or unanimity if amending against the Commission's opinion), the act is adopted; otherwise the Council adopts its first-reading position. (2) Second Reading (3 + 1 months): EP may approve (or take no action -> adopted), reject by a majority of its component members (act fails), or amend by a majority of its component members. Council approval requires unanimity on amendments receiving a negative Commission opinion. If the Council does not approve all EP amendments within 3 + 1 months, a Conciliation Committee (equal numbers of Council representatives and MEPs) is convened within 6 + 2 weeks. (3) Third Reading: if Conciliation agrees a joint text within 6 + 2 weeks, EP (simple majority of votes cast) and Council (QMV) have 6 + 2 weeks to adopt it.

Delegated Acts (Art. 290 TFEU): non-legislative acts of general application adopted by the Commission to supplement or amend certain non-essential elements of a legislative act. They do NOT use Comitology; instead, the EP and Council exercise ex-post control and may individually revoke the delegation or object to a delegated act (by EP majority of component members or Council QMV). Implementing Acts (Art. 291 TFEU): adopted when uniform conditions are needed to implement legally binding Union acts. Implementing powers normally go to the Commission, exceptionally to the Council under Article 291(2). Member State committees control the Commission’s exercise under Regulation 182/2011 through advisory or examination procedures. A negative examination opinion normally blocks the draft, subject to the regulation’s further procedures and urgent exceptions; this is not a power to amend essential legislative elements.

The MFF (binding spending ceilings for at least 5 years, the current framework covers 2021–2027) is adopted under Art. 312(2) TFEU by Council unanimity after obtaining the consent of the European Parliament (acting by a majority of its component members). The Own Resources Decision (Art. 311 TFEU) sets the EU's revenue sources and requires Council unanimity after consulting the EP, PLUS formal approval/ratification by all 27 Member States in accordance with their constitutional requirements. The four current Own Resources are: (1) Traditional Own Resources (customs duties, with Member States retaining 25% for collection costs); (2) VAT-based resource (0.30% call rate, base capped at 50% of GNI); (3) Non-recycled plastic packaging waste (€0.80/kg); and (4) GNI-based balancing resource (largest share).

Under Art. 314 TFEU, the Commission submits the Draft Budget by 1 September; the Council adopts its position by QMV by 1 October; the EP has 42 days to approve or amend (by majority of component members). Disagreement triggers a 21-day Conciliation Committee (27 Council + 27 MEPs) to agree a joint text, followed by 14 days for adoption. If the Council rejects the joint text but the EP approves, within 14 days of the Council rejection the EP may confirm all or some of its earlier amendments by a majority of component members AND three-fifths (3/5) of votes cast; unconfirmed headings retain the conciliation text; the EP President declares the budget definitively adopted. Under Art. 315, if the budget is not adopted by 1 January, monthly spending per chapter is capped at one-twelfth (1/12) of the prior year's budget or draft budget (whichever is lower). Under Art. 319, the EP alone grants annual budgetary discharge to the Commission on a QMV recommendation from the Council. The provisional-twelfths ceiling is the default: Article 315 also allows Council-authorized excess expenditure under its conditions, with Parliament able to reduce it.

NextGenerationEU authorised the Commission to borrow up to €750 billion (2018 prices) on capital markets. Its centrepiece, the RRF (Regulation 2021/241, concluding in 2026), is performance-based rather than cost-reimbursement-based: funds are disbursed only when Member States achieve pre-agreed qualitative milestones and quantitative targets in their national plans, which must allocate at least 37% of spending to climate action and at least 20% to the digital transition; the digital target excludes the REPowerEU chapter, while that chapter has its own 37% climate requirement. Under Regulation (EU, Euratom) 2020/2092, when breaches of the rule of law in a Member State affect or seriously risk affecting the sound financial management of the EU budget in a sufficiently direct way, the Council — acting by QMV on a Commission proposal — may suspend or reduce Union budget commitments or payments.

The Four Freedoms are the free movement of goods (Arts. 28–37), persons/workers & establishment (Arts. 45–55), services (Arts. 56–62), and capital/payments (Arts. 63–66, uniquely applying erga omnes to third countries). In free movement of goods: Dassonville defines MEQRs broadly as any trading rule capable of hindering intra-EU trade directly/indirectly, actually/potentially; Cassis de Dijon establishes Mutual Recognition and 'mandatory requirements' (rule of reason) for indistinctly applicable measures; Keck excludes non-discriminatory 'certain selling arrangements' from Art. 34 TFEU if equal in law and fact. Under the European Climate Law (Regulation (EU) 2021/1119), the EU is legally bound to reach climate neutrality (net-zero GHG emissions) by 2050 and reduce net GHG emissions by at least 55% by 2030 compared to 1990 levels.

In EPSO Verbal Reasoning (20 questions / 35 minutes = 105 seconds per item), the provided passage is the entire universe of verifiable truth. You must suspend external real-world EU knowledge and classify every statement into one of three categories: (1) Definitively True (logically entailed or directly restated by the passage), (2) Definitively False (directly contradicted by the passage), or (3) Cannot Be Deduced (requires an unstated assumption, extrapolation, or outside fact). For a question asking what follows from the text, an option needing outside facts is unsupported. A valid inference need not repeat the passage verbatim. These three analytical categories are a study method, not a claim that every official item uses a three-button response format.

Universal/Absolute terms ('all', 'every', 'always', 'never', 'exclusively', 'solely', 'must', 'guarantees') allow zero exceptions: they can be falsified by a single counterexample and are not justified by a partial or majority statement alone; assess all premises and any explicit conditions ('most', 'many', 'often', 'some', 'may', 'can'). Conversely, a universal rule ('All accredited agencies submit biannual audits') validly entails a partial or existential statement ('Some accredited agencies submit biannual audits'), provided the group exists in the text. Replacing 'may' or 'most' with 'must' or 'all' is the classic Degree Inflation distractor trap.

Given a conditional rule 'If P, then Q' (P -> Q, where P is a sufficient condition and Q is a necessary condition): (1) Valid Equivalence — the Contrapositive ('If not Q, then not P', ~Q -> ~P) is always logically guaranteed. (2) Formal Fallacy 1 — Affirming the Consequent ('Q occurred, therefore P occurred') is invalid because other factors could cause Q. (3) Formal Fallacy 2 — Denying the Antecedent ('Not P, therefore not Q') is invalid. Translation rules: 'P only if Q' means P -> Q (Q is necessary); 'Unless R, S occurs' means 'If not R, then S' (~R -> S).

When a passage reports a correlation or temporal co-occurrence ('accompanied by', 'associated with', 'coincided with', 'followed by'), distractors frequently either assert unproven direct causation ('X caused Y') or invert the causal arrow ('Causal Inversion': claiming Y caused X when the text states X led to Y). Similarly, when a passage uses a contrast, exception or condition marker ('however', 'notwithstanding', 'save where', 'insofar as', 'provided that'), distractors often state the baseline rule as unconditional while omitting the explicit exception.

The average budget is 35 × 60 / 20 = 105 seconds per item, not a mandatory per-item limit. One editorial starting plan is 10 seconds to identify the task, 45 to read/map the passage, 40 to evaluate options and 10 to check the answer. Adjust to passage difficulty and remaining time. Two-anchor triangulation means locating both the relevant entity and a distinguishing date, quantity or action, then reading the full surrounding condition. Anchors speed evidence location; matching keywords alone does not prove an answer.

Relative Percentage Change measures proportional movement relative to the original starting base: Percentage Change (%) = ((New Value - Old Value) / Old Value) x 100. For change from an old positive value, divide by that old value; for a comparison, identify the expressly requested reference base. Percentage change from zero is undefined. Percentage Points measure the simple arithmetic subtraction between two percentage figures: if an absorption rate rises from 20% to 25%, the increase is +5 percentage points, whereas the relative percentage increase is ((25 - 20) / 20) x 100 = +25%.

Reverse Percentage (Base Recovery): if a value reaches Final after a +r% increase (or -r% decrease), recover the original base by dividing by the decimal multiplier: Original = Final / (1 + r/100) [or Final / (1 - r/100)]. Never calculate r% of the Final value and subtract/add it! Sequential Compound Changes: multiply the decimal multipliers: Net Multiplier = (1 + r1/100) x (1 + r2/100). An increase of +x% followed by a decrease of -x% for a positive starting value and 0 < x < 100 results in a net loss of -(x^2 / 100)% (e.g., +20% then -20% yields 1.20 x 0.80 = 0.96, a -4% net drop). Reverse division requires a nonzero multiplier; a 100% decrease cannot be uniquely reversed from a final value of zero.

For an overall rate, weight subgroup rates by their relevant denominator: combined rate = Sum(w_i × x_i) / Sum(w_i), with positive total weight. Do not generally average unequal-sized groups as if their weights were equal. Equal weights guarantee the simple and weighted means agree; equal subgroup rates or coincidental cancellation can also make them agree. For equal positive journey distances at positive speeds v1 and v2, average speed = 2 × v1 × v2 / (v1 + v2); use total distance divided by total time for other cases.

Index Numbers (Base Year = 100): while a change from the base year is simply (Index - 100)%, the percentage change between two non-base years with index values I_1 and I_2 MUST use the relative change formula: ((I_2 - I_1) / I_1) x 100. For example, moving from Index 120 to Index 150 is a +30 index-point shift, which equals ((150 - 120) / 120) x 100 = +25% relative growth (not 30%). Ratio Partitioning: if a total T is split in the ratio a : b : c, one part equals T / (a + b + c), and share 'a' equals T x (a / (a + b + c)).

Before touching the on-screen TAO calculator (120 seconds per item), always verify: (1) Table Header Multipliers (e.g., column A in '€ millions' vs. column B in '€ thousands' or 'per 1,000 inhabitants'); (2) Part-to-Part vs. Part-to-Whole wording ('ratio of A to B' = A/B vs. 'A's share of total' = A/(A+B)); (3) Currency Conversion Direction (multiply vs. divide by exchange rate); and (4) Decimal Time Conversion (e.g., 2.4 hours = 2 hours + 0.4 x 60 min = 2 hours 24 minutes, not 2 hours 40 minutes; and 36 minutes = 36/60 = 0.6 hours). The official hurdle is 10/20 across numerical and abstract combined: a numerical score alone cannot guarantee passing. Use practice results to allocate preparation time to both tests.

In the 60-second sprint per item, avoid passive holistic staring and scan systematically via SCOPO: (1) S — Shape (base polygon morphology, straight vs. curved contours); (2) C — Count (sides, vertices, internal dots/pips, line intersections, enclosed compartments, or invariant conservation sums); (3) O — Orientation (clockwise/counterclockwise rotation step vs. axial reflection); (4) P — Position (grid coordinates, perimeter stepping, bounce vs. wrap-around); (5) O — Overlap & Shading (fill cycles, hatching angles, and Boolean intersection rules). Pacing: 0–10s reconnaissance, 10–35s isolate primary attribute & prune options, 35–50s tie-break surviving options, and reserve the final seconds for an answer/check. This SCOPO mnemonic and pacing split are editorial suggestions, not EPSO rules or a compulsory cutoff.

Check Chirality (handedness): trace 3 distinct asymmetric features around the shape's perimeter in clockwise order. A Rigid Rotation (e.g., 45 deg, 90 deg, 135 deg, 180 deg CW or CCW) preserves chirality — the clockwise sequence of features remains identical. An Axial Reflection (horizontal flip across a vertical axis, vertical flip across a horizontal axis, or diagonal flip) inverts chirality into a mirror image, reversing the clockwise feature order to counterclockwise. Two consecutive reflections across perpendicular axes (a horizontal flip + a vertical flip) restore original chirality and equal a 180-degree rotation.

When two geometric layers or grids superimpose: (1) Exclusive OR (XOR / Cancellation): elements present in ONLY ONE layer remain visible, while overlapping elements present in BOTH layers cancel out and vanish (revert to white); (2) AND (Intersection): only elements present in BOTH layers survive; (3) OR (Union): all elements from both layers merge and remain visible; (4) Contrast Inversion: swap black and white in the region specified by the pattern. Inverting an entire binary image is NOT; it is different from XOR of two images. Under Conservation Laws, individual element counts fluctuate across frames while a combined numerical count stays constant (e.g., outer polygon sides + internal dots = 9 in every frame).

Track a plausible attribute, such as a circle moving one corner clockwise per frame, and test it against every given transition. Remove options inconsistent with that rule, then test a second attribute such as arrow direction or shading. Comparing remaining options can suggest which feature deserves attention, but an apparent split among choices is only a hypothesis. It does not reveal the rule by itself, guarantee exactly two survivors, or justify assuming a fixed number of answer choices.

The 40-question, 30-minute Digital Skills test (45 seconds per item, pass mark 20/40, weighted 30% preliminary / 25% final) tests the five DigComp 2.2 areas: (1) Information and Data Literacy (browsing/searching with Boolean operators, evaluating source credibility/CRAAP, managing data/files); (2) Communication and Collaboration (interacting, sharing, eID/eIDAS trust services, netiquette, managing digital identity); (3) Digital Content Creation (developing content, Creative Commons & open-source licensing, copyright, programming/spreadsheet formulas); (4) Safety (protecting devices, personal data/privacy, health/ergonomics, and the environment); and (5) Problem Solving (troubleshooting, identifying needs, creative digital use, competence gaps). DigComp defines 8 proficiency levels grouped as Foundation (1–2), Intermediate (3–4), Advanced (5–6), and Highly Specialised (7–8).

MFA Security: FIDO2/WebAuthn hardware security keys bind authentication cryptographically to the browser origin domain (resisting credential phishing against a different origin), whereas authenticator-app TOTP codes are stronger than SMS OTPs (which are vulnerable to SIM-swapping). 3-2-1 Backup Rule: maintain at least 3 total copies of data, on 2 different media types, with at least 1 copy stored off-site; offline or immutable protection is an additional resilience measure, not a substitute definition of off-site. Cryptography: Symmetric encryption (e.g., AES) uses one shared key for fast bulk encryption; Asymmetric encryption (e.g., RSA, ECC) uses a public/private key pair for key exchange and digital signatures ( under eIDAS, a Qualified Electronic Signature [QES] has the exact legal equivalence of a handwritten signature); Hashing (e.g., SHA-256) is a fixed-length digest used for integrity checking; it is not encryption and does not authenticate the sender without an additional trusted mechanism.

Regulation (EU) 2018/1725 is the EU-institution data-protection framework, supervised by EDPS, with scope exceptions/special rules in Article 2. GDPR applies within its own scope to other controllers, including many public authorities and private entities. Core principles are lawfulness/fairness/transparency, purpose limitation, minimisation, accuracy, storage limitation, integrity/confidentiality and accountability. Article 5 of 2018/1725 lists public-interest/official-authority task, legal obligation, contract, consent and vital interests; it does not include a legitimate-interests basis. GDPR Article 6(1)(f) separately excludes public authorities’ processing in performance of their tasks. Select the actual applicable basis rather than assuming all public-sector processing needs consent.

CC licence elements: BY requires attribution; SA requires shared adaptations to use the same or a compatible licence; NC limits licensed use to noncommercial purposes; ND prohibits sharing adapted material under that licence, not private adaptation itself. CC0 seeks a public-domain dedication with a fallback licence where necessary. Copyleft licences can impose source/licensing duties when covered software is distributed; permissive licences allow broader reuse but still have conditions. Read the exact licence and compatibility rules. For screen comfort, the 20-20-20 reminder suggests a 20-second distant-viewing break every 20 minutes at about 20 feet (6.096 metres). It is practical advice, not a guarantee against eye strain or an EPSO requirement.

If numeric-IP connectivity works but a hostname returns a name-resolution error, investigate the queried name, DNS server configuration, cache and authoritative response. A successful ping does not prove all routing/application paths work, and NXDOMAIN can correctly mean the name does not exist. LLMs generate probabilistic outputs and may invent citations; verify legal claims against authoritative texts. The AI Act distinguishes prohibited practices, specified high-risk systems and transparency duties, while many uses face no extra risk-specific duties. Exact scope, exceptions and phased application dates matter: do not classify every recruitment tool as automatically subject to every high-risk obligation already in force.

In the 40-minute EUFTE (written in Language 2, scored 0–10 with a 5/10 pass mark, weighted 15% in the final ranking), assessors evaluate written communication skills against five official anchors: (1) Structures written communication with a logical flow of ideas; (2) Writes concisely, avoiding unnecessary words and sentences; (3) Presents subject matter in a clear and understandable way; (4) Adapts and tailors writing to suit the intended audience and purpose; and (5) Uses the information provided effectively to address the assignment. Notice EPSO/AD/427/26 explicitly states that the EUFTE is neither a language test nor a test of factual knowledge.

Under Section 4.3.2(e) of Notice EPSO/AD/427/26, EPSO publishes the EU matters documentation on its website ahead of the test date and provides the same documentation again during the test alongside the assignment(s). Because you can study the dossier in advance, prepare a source map in advance, while still reading the actual assignment carefully. One editorial 3-phase time budget is: (1) Minutes 0–8 (Reconnaissance & Outlining): read the assignment twice to fix your role, audience, and every required task, re-skim the pre-studied dossier, and type your section headings directly into the TAO editor; (2) Minutes 8–35 (Active Drafting): draft the opening summary, analytical sections, and recommendations under your headings (~27 min); (3) Minutes 35–40 (Verification & Polish): verify 100% task coverage, check figures against the dossier, and polish clarity.

For briefing-type assignments, one editorial option is 4 sections, adapted to the actual assignment: (1) Header (TO, FROM, DATE, SUBJECT) + Executive Summary / Bottom-Line Up Front (BLUF: 3–4 sentences under 100 words stating context, core policy tension, and primary recommendation); (2) Baseline & Operational Challenges (Task 1); (3) Balanced Options / Stakeholder Appraisal (Task 2); and (4) Concrete, Prioritised Recommendations (Task 3). Avoid 'patchwriting' (copying dossier sentences verbatim) by reframing facts in your own concise words, and maintain impartial EU administrative neutrality by attributing competing stakeholder views objectively ('Industry representatives highlight... whereas environmental NGOs emphasise...') and weighing trade-offs against EU principles such as subsidiarity, proportionality, and Single Market integrity. These are example task headings, not a promise of three official tasks. Follow anonymity and format instructions; do not insert personal identifying details into a template header.
