Q: How do I try a free CIE Computer Science question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CIE IGCSE Computer Science bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CIE Computer Science students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Computer Science questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Computer Science syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Which Boolean identity represents the absorption law?

Accepted Answer

A AND (A OR B) = A — The absorption law states A AND (A OR B) = A, meaning the larger expression is 'absorbed' into just A. Option A incorrectly simplifies to A OR B, ignoring the absorption. Option C misapplies absorption by claiming A OR (A AND B) = A AND B. Option D is nonsensical as Boolean algebra does not use squaring.

Answer

A OR A = A squared

Answer

A AND (A OR B) = A

Answer

A AND (A OR B) = A OR B

Answer

A OR (A AND B) = A AND B
