Direct-proof questions test what counts as proof: definitions applied step by step, with examples illustrating but never substituting. Expect completing half-written proofs (which line justifies the next?), identifying the definition in play (even, prime, divisor), and rejecting 'proofs' that assume the conclusion.
Method: label each line's logical status — given, definition, deduction — and demand a warrant for every transition. If a line needs anything beyond cited facts, the proof is broken there.
Study method: attempt five timed questions, log every miss with its topic code, redo misses from scratch within 48 hours, then re-attempt the topic a week later. Pair each hub with its drill link below and a fortnightly full mock.
Place this topic in the wider test with the syllabus checklist and Paper 1 vs Paper 2, learn the timing system in how to prepare, and check what scores mean in scores explained.
