Use questions to check your understanding

Try a question before opening its mark scheme. Show each step in calculations and check the units, significant figures and scientific terms used in your answer. Compare your response with the marking points to see where you can improve.

In the question bank, filter by year and paper, open the original paper, or use split view to compare a question with its mark scheme. The Write tab lets you work on the question and save writing on this device. Add questions to a custom paper for a focused revision session.
