GCSE Chemistry Topics

125 lessons across 10 units

This is the complete topic map for the AQA GCSE Chemistry course — every unit and topic from the specification in one place: 125 lessons across 10 units, from 4.1 Atomic structure and the periodic table to 4.10 Using resources. Each topic below opens a focused revision lesson, so revision can start from the course as the exam board organises it — not from a guess about what might come up. Lessons marked Higher cover content that only appears on Higher-tier papers; everything unmarked is for all students.

How to revise with this page

Little and often beats cramming. One topic a night, done properly — read it, try the questions, check yourself — moves a grade more than a weekend binge the week before the exam. The list above is deliberately complete so you can tick through it a topic at a time.

Start from what's coming up, not from the beginning. If a class test or mock is near, open the unit it covers and work through those topics first. Between assessments, work through units in order — later topics usually build on earlier ones.

For parents:you don't need to know the subject to help. Ask which topic tonight's lesson was, open it here, and let them teach it back to you — explaining something out loud is one of the most effective revision techniques there is. Signed-in students see ticks appear on this page as topics are completed, so progress through the course is visible at a glance.
