Study Tips
- 1
Learn to derive equations — examiners frequently ask you to show that a formula can be derived from first principles.
- 2
Paper 3 (Practical) requires you to know specific experimental procedures, how to set up apparatus, and how to calculate uncertainties.
- 3
Mark schemes are specific: "current increases" gets 0 marks; "current increases because resistance decreases according to Ohm's law, so I = V/R" gets full marks.
- 4
Past paper mark schemes from Cambridge are the most valuable revision resource — work through them critically.
