GCSE Physics revision covers forces, energy, waves, electricity, magnetism, particle physics, and the structure of the atom. It's the most mathematical of the three sciences: you'll use equations in almost every question. Understanding how to select, substitute, and rearrange equations is the single most important skill for GCSE Physics.
The GCSE Physics exam has two papers. Paper 1 covers energy, electricity, particle model of matter, and atomic structure. Paper 2 covers forces, waves, magnetism, and space physics (AQA only). Each paper is 1 hour 45 minutes. Around 30% of marks are mathematical, which is higher than Biology or Chemistry.
