Key Takeaway

Mechanics + Electricity = 75% of Paper 1. Chemical Change + Organic = 70% of Paper 2. Focus here first.

How to Study Physics

1

Understand the concept

Physics is not memorisation. Draw diagrams, understand why forces act the way they do.

2

Learn the formulas in context

Do not just memorise F=ma. Know when to apply it and what each variable means.

3

Draw free body diagrams

Every mechanics question starts with a diagram. Label all forces, choose a positive direction.

4

Practice calculations

Physics is 80% calculation. Do past paper questions by topic.

How to Study Chemistry

1

Master balancing equations

Every reaction question needs a balanced equation first.

2

Learn organic naming

Organic chemistry is pattern-based. Learn the IUPAC naming rules systematically.

3

Understand reaction types

Acid-base, redox, elimination, substitution – know how to identify each.

Pro Tip

The data sheet is your best friend. You get formulas, constants, and the periodic table. Learn what is on it so you do not waste time memorising things that are given to you.
