GCSE Maths: Formula Recall and Problem-Solving (Foundation & Higher)
High‑yield formula recall, modelled problem types, and timing checks to raise exam performance at both tiers.
Formulae You Must Recall
Area (triangle, circle), Pythagoras, trigonometry (SOH‑CAH‑TOA), compound interest, quadratic formula (if not given), equation of a line (y=mx+c). Flipcards interleave formulas with units and example use.
Model Problem Types
- Algebra: expand/ factorise; solve linear/quadratic; simultaneous equations.
- Ratio/Proportion: unitary method, percentages, best buys.
- Geometry: angle chasing; similar/congruent shapes; circle theorems (Higher).
- Statistics: averages and spread; charts; probability trees.
Worked Examples and Timing
Show step‑by‑step reasoning with checks (units, scale, reasonableness). Practise under timed conditions: e.g., 10 mixed questions in 15 minutes.
