Cambridge IGCSE Chemistry Past Papers — FAQs
Are these IGCSE Chemistry past papers free with answers?
Yes. Every question paper, official mark scheme, examiner report and grade-threshold document here is free. Full model answers written the way examiners award marks — including multiple-choice working — are available in the solved past papers.
Which variant should I download — 1, 2 or 3?
Cambridge sets different variants by time zone. Most students in the Gulf and Middle East sit variant 2 (Papers 22, 42 and 62). If you are unsure, practise variant 2 first; all variants test the same syllabus at the same standard.
What is the difference between the mark scheme and the examiner report?
The mark scheme lists accepted answers and mark allocation. The examiner report explains the mistakes students made in that session, helping you avoid losing the same marks.
What are grade thresholds?
Grade thresholds show the minimum raw mark needed for each grade in a specific exam session. They help you understand how your practice-paper score relates to your target grade.

How to study IGCSE Chemistry — the 5-step method
Based on more than 20 years of teaching IGCSE Chemistry and helping hundreds of students score A and A* in their final exams.
1 · Understanding 🤓 Everything starts here — IGCSE rewards deep understanding of concepts.
- Find the right resources for your exact exam board and syllabus year before you start.
- Use notes that follow the video lectures — it is hard to keep track of lessons without them.
- Making your own notes is time-consuming, and textbooks contain far more detail than the exam needs.
- Science must be interactive: you will never truly understand the experiments until you watch or do them.
- When you understand a concept, it lasts — and in a one-year programme you need it to last.
- Test yourself: if you can explain the concept in your own words, you are ready to move on.
2 · Memorising 📚 A large share of IGCSE marks depends on recall — values, colours, definitions.
- Everyone memorises differently: flashcards, rewriting, or mind maps all work.
- Best approach: annotate the notes or textbook you already use, so you revise from one resource.
- Minimise the time, maximise the gain — and don't get stuck here.
- Most memorisation happens naturally in the next step, as you solve questions.
3 · Reinforcing 🔖 The step that really matters — solving exam questions.
- The beauty of IGCSE is the huge bank of past papers — use it.
- Always start with classified questions on the topic you just studied.
- Be kind to yourself at first: solve with open notes.
- Never solve without checking answers — that wastes the whole exercise.
- Mark schemes are often unclear, which is why written model answers save so much time.
- Highlight your mistakes; they are your fastest route to improvement.
4 · Connecting 🧩 Combining topics the way real exam questions do.
- Questions mixing several topics are common in IGCSE Chemistry — chapters are designed to complement each other.
- Follow the correct syllabus order so the connections build naturally.
- Solve older papers first (usually easier), then move to recent ones.
- Give extra time to your first few papers; time yourself under exam conditions as you reach the recent ones.
5 · Why choose IGCSE Chemistry? 🤔 If you're picking one science, this is the one.
- The syllabus is relatively short compared with IGCSE Biology.
- The questions are straightforward, and exams are predictable if you have solved past questions.
- The new 2026–2028 syllabus makes it more accessible than ever.
