Study Strategy for 90+

1

Triangles and Circles together carry 20 marks — master all theorems with proofs

2

Surface Areas & Volumes (11 marks) is fully formula-based — memorise all formulas

3

Statistics: practice frequency tables and histogram drawing

4

Number system: rationalisation of surds appears every year

5

For geometry proofs: always state the theorem name, given, to prove, construction, and proof
