Cambridge IGCSE Chemistry 0620: Complete Guide to Papers, Core/Extended & Revision
Cambridge IGCSE Chemistry 0620: Your Complete Guide
Cambridge IGCSE Chemistry (0620) develops understanding of chemistry concepts and practical skills. This guide covers Core vs Extended, which papers you sit, practical options, calculator use, and how to prepare.
What is IGCSE Chemistry 0620?
0620 covers particles, bonding, reactions, organic chemistry, and practical techniques. It is widely used for entry to A-Level, IB, and science degrees.
Papers you need to choose
You choose one level:
- Core (grades C–G): Paper 1 (multiple choice), Paper 3 (theory).
- Extended (grades A*–D): Paper 2 (multiple choice), Paper 4 (theory).
You also take Paper 5 (practical) or Paper 6 (alternative to practical). Your school decides which. You cannot mix Core and Extended.
Calculator use
Calculators are allowed in theory and practical papers where calculations are needed. You must show working and use correct units and significant figures.
How hard is 0620? Is it popular?
- Difficulty: Extended is demanding: calculations, equations, and application. Core is less demanding but caps at C. Practical or Paper 6 tests technique and data handling.
- Popularity: 0620 is one of the most popular IGCSE chemistry codes globally.
Top revision tips for 0620
- Practise past papers for Paper 2/4 and your practical option (5 or 6) under timed conditions.
- Learn equations and mole calculations — stoichiometry and balancing equations are core.
- Revise organic chemistry — naming, reactions, and conditions.
- Practise practical-style questions (apparatus, safety, results) if you take Paper 6.
