Also included

• 10 multiple-choice questions in the style of Paper 1/2, with an answer key and reasons
• Practical skills question in the style of the Alternative to Practical paper (Paper 6): a model experiment linking brightness and distance, as astronomers do with supernovae
• Revision checklist so students can track what they know before the exam

Why teachers like it

• Every question is labelled CORE or SUPPLEMENT, so you can set Core-only or Extended work in seconds
• Covers every statement in syllabus section 6 (coverage map included)
