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.
The course is organised into 10 units: 4.1 Atomic structure and the periodic table (15 lessons), 4.2 Bonding, structure, and properties of matter (18 lessons), 4.3 Quantitative chemistry (13 lessons), 4.4 Chemical changes (15 lessons), 4.5 Energy changes (5 lessons), 4.6 The rate and extent of chemical change (11 lessons), 4.7 Organic chemistry (12 lessons), 4.8 Chemical analysis (14 lessons), 4.9 Chemistry of the atmosphere (10 lessons) and 4.10 Using resources (12 lessons). Together that's 125 lessons — the whole course, with nothing skipped and nothing added.
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.
