123 lessons across 7 units
This is the complete topic map for the OCR Gateway GCSE Biology course — every unit and topic from the specification in one place: 123 lessons across 7 units, from Topic B1: Cell level systems to Topic B7: Practical skills. 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.
The course is organised into 7 units: Topic B1: Cell level systems (22 lessons), Topic B2: Scaling up (16 lessons), Topic B3: Organism level systems (27 lessons), Topic B4: Community level systems (10 lessons), Topic B5: Genes, inheritance and selection (19 lessons), Topic B6: Global challenges (21 lessons) and Topic B7: Practical skills (8 lessons). Together that's 123 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.
