How it works
- The question paper opens beside an answer sheet. On a phone they are two tabs.
- Tap a letter for each question. In practice mode a wrong answer turns red and the right letter lights up.
- Finish to see your mark out of 40 and which questions to look at again.
- The papers are Cambridge's own and are shown for practice; our O Level / IGCSE Chemistry tests and mock exams are written by us in the same style.
