A lengthy question about a best-of-three tennis match, but with a twist: The probability of winning a point changed depending on whether the player was serving or receiving. Day 1 — Differentiation practice: 6–8 varied questions
Day 1 — Differentiation practice: 6–8 varied questions (incl. implicit). Day 2 — Integration techniques: substitution, parts, partial fractions (6 problems). Day 3 — Sequences & series + binomial theorem problems (6–8 questions). Day 4 — ODEs and applied calculus (6 problems). Day 5 — Mixed past-paper questions from 2010–2013 (timed 2-hour session). Day 6 — Review mistakes, rewrite solutions neatly; memorise key formulae. Day 7 — Full paper simulation under exam conditions; mark against marking scheme.
