Past papers are the best way to prepare for your Cambridge IGCSE Chemistry (0620) exam. They show you the real question style, the command words examiners use, and how marks are given. This page explains where to find the official papers and how to get the most out of them.

Which papers should you practise?
- Core students: Paper 1 (Multiple Choice) and Paper 3 (Theory)
- Extended students: Paper 2 (Multiple Choice) and Paper 4 (Theory)
- Everyone: Paper 5 (Practical Test) or Paper 6 (Alternative to Practical), depending on what your school enters you for
Tip: 0971 is the same exam graded 9–1, so 0971 papers are good practice too.
How to use past papers (teacher’s tips)
- Revise the topic first using notes, then try questions on it.
- Do full papers under timed exam conditions, with no notes.
- Mark your work strictly with the official mark scheme.
- Write down every mistake and which topic it came from.
- Go back to that topic’s notes, then try similar questions again.
