GCSE Chemistry revision spans the entire material world — from atomic structure and bonding to organic chemistry and chemical analysis. You'll need to understand why reactions happen, how to predict products, calculate masses, and interpret experimental data. It's one of the most interconnected GCSE subjects: understanding bonding helps you understand properties, which helps you understand reactions.
The GCSE Chemistry exam is split into two papers. Paper 1 covers atomic structure, bonding, quantitative chemistry, chemical changes, and energy changes. Paper 2 covers rates of reaction, organic chemistry, chemical analysis, the atmosphere, and using resources. Both papers test recall, application, and extended writing.
