Study Skills Worksheet: Interleaving

Exam preparation lesson 11: Interleaving (mixed practice) · Set 215 · 40 questions

Study tip (Mix it up): Interleaving: mixed sets, old and new topics together, switching topic each question. Blocked: one type, page by page. Read each question for clues: “%” → percentage; “m by m” or tiles → area; “a : b” → ratio; 3/4 → fractions. Block when first learning; mix for revision and exam practice.
