About these tests

Free KS3 science practice tests for Years 7 to 9, written for the key stage 3 programme of study in England: one test each for biology, chemistry and physics, including some calculation questions.

Every question has a short explanation, and each test picks new questions from a larger bank when you try again. The questions are our own: they are not taken from past papers.
