CS Revision

CS Revision helps you revise IB Diploma Computer Science in one focused place: learn a topic, practise it, then review what you got wrong until it sticks.

LEARN EVERY TOPIC STEP BY STEP
• 27 structured topics across Theme A, Theme B and the course components
• Clear explanations, key ideas, worked examples and tables
• Code examples in Python or Java, with syntax highlighting. Choose your language once.
• Standard Level and Higher Level: HL-only material is labelled and can be hidden
• Search, filter and bookmark topics

PRACTISE WITH ORIGINAL QUESTIONS
• Over 1,100 original practice questions written for this app
• Single-answer, multiple-answer, code-output and short-answer questions
• Instant feedback with an explanation for every question
• Quick practice, topic practice and timed Theme A and Theme B practice sets
• Report any answer that looks wrong straight from the question

REVIEW AT THE RIGHT TIME
• A spaced-review queue brings back questions just before you are likely to forget them
• Progress charts, topic mastery and your weakest topics at a glance
• A Due Review widget for your Home Screen
• Optional daily practice reminders at a time you choose

ASK THE QUESTION COACH
Ask a follow-up about the lesson or question you are studying. The Question Coach uses Apple Intelligence on your device, so your questions are not sent to the developer or saved. It needs an iPhone or iPad that supports Apple Intelligence, with Apple Intelligence turned on. Responses are generated and can contain mistakes, so check them against the lesson.

PRIVATE BY DESIGN
• No account or sign-in
• Your study profile and progress can sync between your iPhone and iPad through your own private iCloud
• No advertising, no tracking and no third-party analytics
• Export your progress or reset it at any time

FREE AND FULL ACCESS
Free: a selection of lessons and practice questions with explanations, up to three due review questions at a time, and one Question Coach conversation.
Full Access (one-time in-app purchase): every lesson and question, unlimited practice and review, timed practice sets and unlimited Question Coach conversations. It is a single purchase with no subscription, and you can restore it on your other devices.
