About the Hamburg Zentralabitur Computer Science Exam

Informatik in the Hamburg Zentralabitur is a zentrales Prüfungsfach under Bildungsplan Studienstufe 2022 and A-Heft 2026. Candidates must complete Aufgabe I (OOP modelling and programming) and choose either Aufgabe II (data security in distributed systems) or Aufgabe III (intelligent search procedures), working in Python or Java and, at eA, also Scheme or Haskell. Working times are gA 255 / eA 300 minutes with a non-programmable calculator and spelling dictionary allowed. This free bank offers 100 original English MCQs covering OOP/UML, cryptography, and search algorithms/data structures; it cannot replace timed German constructed-response work.

Exam sponsor: Behörde für Schule, Familie und Berufsbildung (BSFB), Freie und Hansestadt Hamburg; schools administer under Hamburg Abitur regulations. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

For Informatik in 2026 (A-Heft 2026), the Fachlehrkraft receives three Aufgaben in all available programming-language variants: I Objektorientierte Modellierung und Programmierung; II Datensicherheit in verteilten Systemen; III Intelligente Suchverfahren. The Prüfling receives all three, chooses one of II or III, selects language(s)—Python or Java at both levels; eA additionally Scheme or Haskell—and completes Aufgabe I plus the chosen II/III, noting which Aufgabe was done in which language. Completeness of Blätter/Anlagen must be checked before starting. Bearbeitungszeit: gA 255 minutes, eA 300 minutes; no separate Lese- or Auswahlzeit. Hilfsmittel: non-programmable non-graphing calculator and Rechtschreibwörterbuch. Curriculum basis: Bildungsplan Studienstufe 2022, Rahmenplan Informatik. Official language is German; scoring uses Erwartungshorizont criteria with conversion to Notenpunkte 0–15. This OpenExamPrep bank is an English-language MCQ study adaptation—not an official translation or format simulation.

Time Limit

Grundlegendes Anforderungsniveau 255 minutes / erhöhtes Anforderungsniveau 300 minutes. No separate Lese- or Auswahlzeit (A-Heft 2026 — Informatik). Written Abitur Haupttermin window 20.04.–08.05.2026 (BSFB).

Passing Score

Subject performances use Notenpunkte 0–15 under Hamburg Abitur Bewertung rules. The overall Abitur is decided by the Gesamtqualifikation; do not treat this MCQ bank as having an official cut score.

Exam / Certification Fees

No separate statewide per-subject fee is published for regular school Abitur candidates; any costs depend on school/Land pathway rather than a published Informatik exam price.

Hamburg Zentralabitur Computer Science: Suggested Study Strategy

1Treat Aufgabe I as non-negotiable: drill OO modelling, UML class diagrams, and Python/Java implementation vocabulary every week.
2Decide early whether your stronger optional paper is II (security/crypto) or III (search/graphs) and still keep the other as backup.
3For eA, practise Scheme or Haskell recursion (including end recursion) and functions-as-parameters alongside Java/Python OOP.
4Memorise RSA toy calculations, Kerckhoffs’ principle, and Diffie–Hellman key-exchange steps for Aufgabe II.
5For Aufgabe III, compare BFS vs DFS, Dijkstra with priority queues, Kruskal for MSTs, and A* heuristics at eA.
6Learn verbindliche Operatoren (beschreiben, erläutern, implementieren, beurteilen, …)—the official paper is constructed-response in German.
