Twenty exam-board style multiple-choice questions spanning every KS3 Science unit — Biology, Chemistry & Physics — with full worked solutions.
This paper tests one core idea from each major KS3 Science topic. For every question you'll first see the concept and the key fact to memorise, then answer the real exam-style question. Feedback appears the instant you choose — correct answers spark; wrong answers explain why, immediately. Your final mark and full worked answers appear at the end.
Every question, the correct answer, and the full reasoning — including why each distractor is wrong.
