O Level

Computer Science

Syllabus 2210Cambridge International

Cambridge O Level Computer Science (2210) introduces programming, algorithms, data representation, networks and ethical issues. Two papers — theory and practical problem-solving. Essential foundation for A Level Computer Science, Software Engineering and Data Science.

Key topics

Data representation — binary, hex, character sets, images, sound
Communication & networks — LAN/WAN, packet switching, security
Hardware — CPU, RAM, storage, input/output devices
Software — system & application, programming languages
Algorithm design, pseudocode & flowcharts
Programming concepts, databases, ethics

Exam tips

01Practice writing pseudocode by hand — most students lose marks on indentation and syntax.
02Memorise binary/hex conversion shortcuts.
03For paper 2, plan your algorithm before coding — trace tables save you in tricky questions.
04Practice past papers from at least the last 5 sessions — pattern recognition is half the battle.
05Master the CAIE command words: define, explain, evaluate, calculate, describe, compare, state.
