Sample KMA Cadet 1st-Stage Exam Practice Questions

Try these sample questions to review concepts for the KMA Cadet 1st-Stage Exam exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In Korean philosophical hermeneutics, Toegye Yi Hwang (이황) and Yulgok Yi I (이이) developed distinct interpretations of the Four-Seven Debate (사칠이기논변). Which statement accurately characterizes Yulgok's position on Qi and Li (기발이승일도설)?
A.Only Qi issues forth actively while Li rides upon it (氣發而理乘之), maintaining that both the Four Beginnings (사단) and Seven Emotions (칠정) originate from Qi's movement.
B.Li issues forth independently of Qi to generate moral perfection, while Qi acts only as an obstructive physical impediment.
C.The Four Beginnings issue purely from transcendent Li, whereas the Seven Emotions issue exclusively from material Qi.
D.Li and Qi constantly transform into each other through physical condensation and cosmic evaporation.
Explanation: Yulgok Yi I formulated the doctrine of 'Gi-Bal-I-Seung-Il-Do' (기발이승일도설), asserting that active agency in cosmic issuance belongs solely to Qi, with Li riding upon Qi without independent physical issuance. Thus, both the morally pure Four Beginnings (사단) and the general Seven Emotions (칠정) represent emotional manifestations where Qi issues and Li rides.
2In an expository essay analyzing economic market failures, what is the primary mechanism through which asymmetric information (정보의 비대칭성) generates adverse selection (역선택)?
A.Before transactions occur, uninformed market participants face an adverse product pool because higher-risk sellers dominate market offerings at average prices.
B.After contracts are signed, agents alter their behavior to take excessive risks because losses are borne by other parties.
C.Government price caps force suppliers to exit the market, resulting in long-term structural supply shortages.
D.Monopolistic firms restrict output below socially optimal levels to capture deadweight consumer surplus.
Explanation: Adverse selection occurs prior to transaction completion (ex-ante) when one party possesses hidden information regarding product quality or risk characteristics. Sellers of high-quality goods withdraw when buyers offer only average market prices, leaving predominantly low-quality goods in the market.
3In a scientific reading passage on cellular neurobiology, how does the resting membrane potential (휴지 전위) of a mammalian neuron return to baseline following the repolarization phase of an action potential?
A.Voltage-gated potassium channels close and the Na+/K+-ATPase pump actively restores resting ionic gradients by pumping 3 Na+ out and 2 K+ in.
B.Voltage-gated sodium channels remain open while calcium efflux hyperpolarizes the cytoplasm back to positive equilibrium.
C.Chloride ions passively diffuse out of the cell through electrical attraction until sodium ions equalize.
D.The axon terminal completely hydrolyzes neurotransmitters to trigger immediate membrane depolarization.
Explanation: Following the repolarization phase driven by K+ efflux, the neuron briefly undergoes afterhyperpolarization. The Na+/K+-ATPase pump actively hydrolyzes ATP to export 3 Na+ ions and import 2 K+ ions against their electrochemical gradients, re-establishing the standard resting potential around -70 mV.
4In Dasan Jeong Yak-yong's (정약용) treatise 'Gyeongse Yupyo' (경세유표), which institutional reform did he propose regarding land tenure and rural agrarian structure?
A.The Yeojeonje (여전제), where village land is collectively owned and worked under a village head, with harvest distributed according to labor days worked.
B.The Gwajeonbeop (과전법), where all agricultural land is permanently allocated to central civil officials based on court rank.
C.Complete privatization of communal mountain lands to encourage unconstrained merchant tenancy contracts.
D.Abolition of all agricultural taxation in exchange for universal mercantile salt monopolies.
Explanation: Dasan articulated the Yeojeonje (여전제 / 閭田制) in his reformist writings, proposing communal landholding organized around village units (yeo / 閭). Under this system, villagers farm collectively, the village head records daily labor inputs, and after deducting public taxes, the yield is distributed proportionally to days worked.
5In a philosophical text exploring epistemological skepticism, what is René Descartes' core rationale for introducing the 'Evil Demon' (악령) hypothesis in his Meditations on First Philosophy?
A.To extend doubt beyond sensory perception to mathematical and geometric truths that appear self-evident.
B.To prove that demonic entities govern physical natural laws without mathematical regularity.
C.To demonstrate that human sensory organs provide completely infallible representations of external objects.
D.To argue that empirical experimentation is superior to deductive rational intuition.
Explanation: Descartes introduced the hypothetical malignant demon (genius malignus) to push methodological doubt to its radical limit. While the dream argument undermined sensory empirical beliefs, the evil demon hypothesis systematically doubted even a priori mathematical propositions (such as 2 + 3 = 5), preparing the ground for the indubitable 'Cogito, ergo sum'.
6In an expository passage on astronomical physics, why does the orbital speed of a planet increase as it approaches perihelion (근일점) along an elliptical orbit?
A.Gravitational potential energy decreases as distance decreases, requiring kinetic energy and orbital speed to increase to conserve total mechanical energy.
B.Centrifugal forces generate additional mass that pushes the planet forward along its orbital trajectory.
C.Solar radiation pressure concentrates behind the planetary hemisphere at perihelion to accelerate its motion.
D.The gravitational constant increases proportionally to the inverse cube of orbital separation.
Explanation: By Kepler's second law (conservation of angular momentum) and the conservation of mechanical energy, a planet moving along an eccentric orbit loses gravitational potential energy (U = -GMm/r) as r decreases, which must be converted into kinetic energy (K = 1/2 mv^2), maximizing velocity at perihelion.
7In a legal philosophy passage on constitutional interpretation, which concept characterizes the 'Rule of Law' (법치주의) as substantive (실질적 법치주의) rather than merely formal (형식적 법치주의)?
A.The content of legislation must conform to fundamental human rights, constitutional justice, and proportional balance, not merely follow formal legislative passage.
B.Statutes enacted through majority parliamentary voting are valid regardless of human rights compatibility.
C.Executive decrees supersede statutory enactments whenever administrative expediency is required.
D.Judicial courts are prohibited from reviewing the constitutionality of legislative statutes.
Explanation: Substantive rule of law (실질적 법치주의) insists that laws must not only be enacted via procedurally legitimate legislative processes, but their substantive content must also uphold fundamental rights, democratic justice, and constitutional proportionality. Formal rule of law focuses solely on procedural regularity.
8In a technology reading text analyzing public-key cryptography (공개키 암호화), how does the RSA algorithm ensure secure message transmission between sender and receiver?
A.The sender encrypts data with the receiver's public key, and only the receiver's private key derived from large prime factorization can decrypt it.
B.Both parties share an identical secret symmetric key transmitted over an unencrypted radio channel.
C.The message text is converted into analog waveforms that cannot be parsed by digital receivers.
D.The public key decrypts the message while the private key is published openly to the network directory.
Explanation: Asymmetric cryptography like RSA uses mathematically paired keys. Anyone can encrypt a message using the recipient's openly published public key, but decryption is computationally infeasible without the recipient's private key, which exploits the difficulty of prime factorization of large composite integers.
9In an analytical passage examining game theory, what defines a Nash Equilibrium (내시 균형) in a non-cooperative simultaneous game?
A.A strategy profile where no player can unilaterally increase their expected payoff by deviating from their chosen strategy, given the choices of all other players.
B.An outcome where total collective payoffs are maximized regardless of individual incentives to defect.
C.A situation where all players choose the strategy that minimizes their opponent's absolute maximum score.
D.A round where players collude legally through enforceable external contractual commitments.
Explanation: A Nash Equilibrium represents a state of strategic stability in which each player's chosen strategy is an optimal response to the strategies chosen by all other players. No individual player has an incentive to unilaterally alter their strategy.
10In a linguistic passage on generative grammar (생성문법), what does Noam Chomsky's distinction between 'competence' (언어 능력) and 'performance' (언어 수행) signify?
A.Competence is the internalized system of linguistic knowledge possessed by a native speaker, whereas performance is the actual production and comprehension of speech in concrete situations.
B.Competence refers to writing proficiency in formal standardized exams, whereas performance denotes spoken fluency.
C.Competence is acquired purely through behavioral habituation, whereas performance is determined by universal grammar.
D.Competence measures foreign language vocabulary size, whereas performance evaluates phonetic accent.
Explanation: In Chomskyan linguistics, linguistic competence (언어 능력) refers to the ideal native speaker-hearer's tacit cognitive knowledge of grammatical rules and language structure. Linguistic performance (언어 수행) is the actual real-time deployment of this knowledge, which is subject to memory limitations, distractions, and speech errors.

About the KMA Cadet 1st-Stage Exam Exam

The Korea Military Academy Cadet Entrance Exam (육군사관학교 입시) Stage 1 written examination is administered jointly by the four South Korean military academies: Korea Military Academy (KMA), Korea Naval Academy (KNA), Korea Air Force Academy (KAFA), and Armed Forces Nursing Academy (AFNA). Co-developed under the Ministry of National Defense, all four academies administer the identical test booklet nationwide on the same Saturday in late July. The academic scope comprises Korean Reading and Literature (독서, 문학; 30 items, 50 minutes), English I and II (30 items, 50 minutes, without listening), and Mathematics I, II, and electives (30 items, 100 minutes). OpenExamPrep provides an independent 100-item English four-option multiple-choice study bank weighted across these three core academic disciplines with genuine mathematical calculations. It is a study aid and concept builder, not an official military translation or simulation of physical and interview stages.

Exam sponsor: Korea Military Academy (육군사관학교) with the Naval, Air Force and Armed Forces Nursing Academies, which jointly set the first-stage paper. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Stage 1 (joint written paper): 국어 (독서·문학, 30 items, 50 min), 영어 (영어Ⅰ·Ⅱ, 30 items, 50 min, no listening) and 수학 (수학Ⅰ·Ⅱ plus one elective, 30 items, 100 min). Candidates are ranked on standardised scores — the Korea Military Academy advances five times the quota for men and eight times for women in each stream — and Stage 2 then covers the medical examination, fitness test and interview. Final admission combines Stage 1 and Stage 2 with the high school record and, in the comprehensive track, CSAT (수능) results.

Time Limit

200 minutes of testing on one morning — Korean 50 min, English 50 min, Mathematics 100 min (09:10–13:30)

Passing Score

No fixed percentage pass mark. Stage 1 advancement is by standardised-score rank within each academy's published multiple of the quota (five times for men and eight times for women at the Korea Military Academy).
