01Programming and Software Development
This shared-core programming guide covers language constructs, object-oriented design, development processes, and testing. Practice reading and debugging code: predict output, identify a scope or logic error, and choose tests that expose faults.
367 words, about 2 min02Computational Thinking and Problem Solving
This shared-core guide develops decomposition, pattern recognition, abstraction, algorithm design and tracing, and evaluation. Use pseudocode and search/sort scenarios to practice predicting output, identifying missing steps, and justifying complexity.
361 words, about 2 min03Data representation, arrays, lists, trees and graphs
This domain covers how numbers, text, images and sound are encoded in binary, and how collections of data are organised so operations are efficient. Calculations - file sizes, two's complement ranges, normalised floating point - are examined as much as definitions.
595 words, about 3 min04Data, Databases, and Information Retrieval
Data questions move from raw facts to organized, queryable information. In the relational model, tables have rows (records) and columns (attributes); keys enforce identity and relationships.
659 words, about 3 min05Automata, formal languages and computability
Der Bereich Theoretische Informatik prüft, wie man Sprachen formal beschreibt und welche Maschinen sie erkennen. Erwartet werden das Entwerfen und Minimieren endlicher Automaten, die Umwandlung zwischen regulären Ausdrücken, Grammatiken und Automaten, die Einordnung in die Chomsky-Hierarchie sowie Grundbegriffe der Berechenbarkeit wie Entscheidbarkeit und Halteproblem.
477 words, about 2 min06Identity, access and cryptographic protection
This domain tests the identity lifecycle and the mechanisms that turn an identity into an authorised action. Expect questions that separate authentication from authorisation and that ask which access control model fits a scenario.
871 words, about 4 min07Computing Systems
This shared-core guide covers hardware, operating systems, storage, virtualization, system security, and networking. Practice explaining instruction execution, memory, resource management, and controls against specified risks.
727 words, about 4 min08Impacts of Computing
Impacts questions ask you to reason about how computing changes people, institutions, and environments-not just whether a tool works. Know the digital divide (access, affordability, skills, and broadband quality), accessibility and universal design, automation and job displacement/creation, gig work, surveillance, privacy, misinformation, algorithmic bias, filter bubbles, e-waste, energy consumption, intellectual property, open source, and digital citizenship.
