GCSE Revision Checklist: Biology, Chemistry, and Physics
GCSE Science exams (AQA, Edexcel, OCR) cover a defined list of topics for each of the three sciences. Using a checklist rather than re-reading your textbook is the most efficient revision approach: you identify exactly which topics you know and which you don't, then target your time where it's needed.
This article gives you the highest-yield topics for each science, RAG-style (Red/Amber/Green) checklist format, and a 6-week revision plan.
How to Use This Checklist
For each topic, rate yourself:
- 🟢 Green: Can explain this confidently, answer exam questions without notes
- 🟡 Amber: Know it broadly but would struggle on a specific exam question
- 🔴 Red: Unsure or haven't revised yet
Focus your revision exclusively on 🔴 Red topics. 🟡 Amber topics need one quick review pass. Don't re-revise 🟢 Green topics — that time is wasted.

Frequently Asked Questions
What are the most important GCSE Biology topics?
The highest-yield topics across AQA, Edexcel, and OCR are: cell biology (always tested), photosynthesis and respiration equations, the immune response and vaccination, hormonal coordination (insulin, adrenaline, reproductive hormones), and inheritance (Punnett squares, dominant/recessive alleles). These appear in at least one question on virtually every past paper.
What's the difference between GCSE Combined Science and Triple Science?
Combined Science (Double Award) covers all three sciences but at reduced depth — you receive two GCSEs. Triple Science covers each subject fully and awards three separate GCSEs. The checklist above covers Triple Science; Combined Science students can focus on the core topics only (approximately 60–70% of the lists above).
How many past papers should I do for GCSE science?
Aim for 3–5 past papers per subject under timed conditions. AQA, Edexcel, and OCR publish free past papers with mark schemes on their websites. Past papers from the last 5 years are most relevant — topics and question styles are most consistent with your upcoming exam.
How long before GCSE exams should I start revising?
Starting 8–12 weeks before your first science exam gives you enough time to cover all topics, do past paper practice, and address weak areas. Starting 4 weeks before is manageable but leaves no room for setbacks. Using the RAG checklist approach from the start of revision prevents wasted time on topics you already know.
The Bottom Line
The RAG checklist approach turns GCSE science revision from a vague "read through your notes" into a targeted, measurable process. Red topics get attention; Green topics are left alone.
Action step: Print or copy the checklist for your weakest science subject. Go through every topic and mark it Red, Amber, or Green right now. Count your Red topics. That number tells you exactly how much focused revision time you need. Start with the first Red topic tomorrow.
