IMPORTANT: these significant figures multiple choice questions are aimed at chemistry students. If you need to practice significant figures for A-level maths these are not the best questions for you.

This quiz contains 10 multiple choice questions to help you test your knowledge and understanding of significant figures and rounding, to help you prepare for A-level Chemistry.

All of the questions are answerable based on what you learned at GCSE, so if you struggle to answer any of them you have a gap in your knowledge that you need to fill in.

Remember, significant figures and decimal places are not the same thing. So if you have any confusion here, you need to revisit your GCSE maths books. This post may also help you.
