210 lessons across 10 units
This is the complete topic map for the Edexcel GCSE Chemistry course — every unit and topic from the specification in one place: 210 lessons across 10 units, from Common topics (Paper 1 & 2) to Topic 9 Separate chemistry 2. 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: Common topics (Paper 1 & 2) (6 lessons), Topic 1 Key concepts in chemistry (47 lessons), Topic 2 States of matter and mixtures (8 lessons), Topic 3 Chemical changes (22 lessons), Topic 4 Extracting metals and equilibria (15 lessons), Topic 5 Separate chemistry 1 (23 lessons), Topic 6 Groups in the periodic table (16 lessons), Topic 7 Rates of reaction and energy changes (12 lessons), Topic 8 Fuels and Earth science (22 lessons) and Topic 9 Separate chemistry 2 (39 lessons). Together that's 210 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.
