Q: Is Kramizo really free for OCR Mathematics 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 Mathematics questions aligned to the OCR GCSE syllabus?

Every question is written against the published OCR GCSE Mathematics 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 OCR past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

The sum of two numbers is 45 and their difference is 9. If the larger number is represented by x and the smaller by y, what is the value of x?

Accepted Answer

27 — Award 1 mark for 27. The equations are x + y = 45 and x - y = 9. Adding these equations: 2x = 54, so x = 27. B is the value of y. C is incorrect calculation. D is the difference, not the larger number.
