OCR GCSE Combined Science (Gateway / Twenty First Century): P6: Radioactive Materials FAQ
Is Kramizo free for OCR GCSE students preparing for Combined Science (Gateway / Twenty First Century)?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix P6: Radioactive Materials practice with other Combined Science (Gateway / Twenty First Century) topics or even switch to a totally different OCR subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the P6: Radioactive Materials questions aligned to the official OCR GCSE Combined Science (Gateway / Twenty First Century) syllabus?
Every question is written against the published OCR GCSE Combined Science (Gateway / Twenty First Century) specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real OCR paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from OCR.
How is P6: Radioactive Materials typically tested on OCR GCSE Combined Science (Gateway / Twenty First Century) papers?
P6: Radioactive Materials appears across multiple question types on real OCR GCSE Combined Science (Gateway / Twenty First Century) papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
