How Can I Get an A* in A-Level Physics?

Hey everyone,

I’ve been working hard on my Physics Paper 4, and my latest mock results are: 44 → 55 → 50 → 73

I’m happy with the progress, but I really want to push for an A* in my A-Levels( I got 84 marks in AS level)Does anyone have any advice on:

Effective revision techniques for Paper 4?

The best resources for tricky topics?

How to improve my exam technique and avoid careless mistakes?

Any tips from those who have achieved an A* (or made big improvements) would be really appreciated
