Tips
A-Level Physics (9702) goes from measurement and motion all the way to quantum physics. The biggest jump from IGCSE is the algebra: you must rearrange and combine equations, not just remember them.
AS year: mechanics, waves, electricity, and the start of particle physics. A2 year: circular motion, gravitational, electric and magnetic fields, oscillations, thermodynamics and nuclear physics.
Read one topic, then do questions on it straight away. Physics does not stick from reading. When an answer is wrong, ask yourself: was it the physics or the algebra? The two need different fixes.
