Overview of A Level Biology and Revision Strategies in 2025
A Level Biology can be a challenging science course covering life at the molecular, cellular, and organism level.
For every exam board, whether AQA, OCR, Edexcel, or WJEC, your course will test your understanding of core biological concepts and apply your knowledge to them through exam questions.
The A Level Biology Topics You Need to Master
Every exam board differs, so be sure to check their syllabus specifically. These are the key topics likely to be featured in your A Level Biology exams.
How the Exams Boards Compare
Each exam board differs slightly. Here's what each tends to focus on for reference:
AQA
- Focus on application of biological concepts
- Strong emphasis on data analysis
- Includes extended response questions
OCR
- Focus on data interpretation and experimental design
- Emphasis on mathematical biology and practical application
- Analytical and investigative question style
Edexcel
- Focus on real-world biological contexts
- Use of structured questions and lab-based scenarios
- Clear connection to practical skills
WJEC
- Focus on scientific explanation and understanding of biological processes
- Analysis of experimental data and design
- Testing of practical knowledge through scenario-based questions
Top A Level Biology Revision Resources (2025)
The right resources can make all the difference when you prepare for your A Level Biology exams in 2025.
With so many topics to consider, you must ensure that the resources you use are up-to-date and include the right topics.
Here are some of our favourites, but if you have resources that helped a lot in GCSE, be sure to check if the people who made them have A Level versions.
Recommended Textbooks and Official Guides
Books may seem like the oldest method of instruction in 2025, but exam boards and education companies still swear by them.
After all, the biggest advantage of a book is that you can't access social media on it. It's much easier to stay focused when reading from print than on a phone, laptop, or computer that spends all its time trying to send you notifications and distract you.
- AQA A Level Biology: AQA Biology A Level Student Book by Nick Dixon and Adam Boxer.
- OCR A Level Biology (Biology A): OCR A Level Biology A Student Book by Adrian Schmit et al.
- Edexcel A Level Biology: Edexcel Biology A (Salters-Nuffield) Student Book — ideal for topic-specific revision.
- WJEC A Level Biology: WJEC/Eduqas Biology for A Level Year 1 & 2 Student Book — tailored to the WJEC specification.
Check for the latest 2025 editions to ensure all content is aligned with current exam specifications.
Free Online Revision Notes and Topic Summaries
There are so many high-quality and free revision materials online. Look for notes (though we recommend making and reading your own) on your study topics.
- Physics & Maths Tutor (Biology Section): Concise revision notes, past paper questions, and mark schemes organised by topic.
- Save My Exams: Exam board-specific revision notes for AQA, OCR, and Edexcel, including predicted questions and model answers.
- Seneca Learning: Free interactive revision courses covering all core topics, practical techniques and exam-style questions.

Best YouTube Channels and Podcasts for Biology Revision
Visual learners will appreciate YouTube videos, while aural learners may enjoy podcasts. For tricky topics like meiosis, mitosis, genetic mutations, protein synthesis, or heart and blood transport, it can help to see visuals or hear them explained.
- Amoeba Sisters: Fun, animated videos explaining core concepts like DNA, cells, and enzymes.
- SnapRevise Biology: Exam-specific breakdowns with past paper questions and exam tips.
- Primrose Kitten: Focused biology revision sessions, past paper walk-throughs, and practical advice.
- Biology with Dr. Weston (Podcast): Advanced discussion of A Level topics and how to approach exam questions.
Here's the Amoeba Sisters' explanation of cell transport.
Find A Level Biology Past Papers and Exam Questions
While Biology A Level courses are designed to teach you about biology, you're ultimately being taught how to pass the A Level Biology exam.
The best way to prepare for your A Level Biology exam is by reviewing past papers (provided the questions and topics are still relevant) and sample questions provided by the exam boards.
You can find them and official mark schemes on the exam boards' websites.
- AQA Past Papers: Official AQA Biology past exam papers, mark schemes, and examiner reports.
- OCR Past Papers: Access to OCR A and B (Advancing Biology) past papers and practical questions.
- Edexcel Past Papers: Salters-Nuffield Biology A past exam papers and model answers.
- WJEC Past Papers: Past paper bank for WJEC A Level Biology, including practical-based questions.
Focus on practical/data interpretation questions and topics like enzymes, respiration, transport systems, and genetic problems, which frequently appear in exams.
Past papers aren't just great for learning the questions and the topics in the exams, they're a way to get used to exam timing.
When you sit past papers, try to do them in exam conditions. You mightn't always have several hours to do them, but it's recommended that you do them in complete silence with only the resources and materials you'd be allowed to use on the day. Working with a biology tutor near me can help you to go over any difficult concepts and boost your biology grade.
Planning and Structuring Your A Level Biology Revision
Once you have your exam topics and dates, you can assemble appropriate resources and plan your revision.
Organise your time carefully, ensuring you focus on studying little and often over trying to study for several biology exams simultaneously.
Step 1: Break Down the Course
Divide and conquer to make revision more manageable. Divide the course into key topics to make revision less overwhelming.
Step 2: Create a Weekly Revision Timetable
Create a revision timetable that outlines what you'll study and when. Be sure to mix things up to ensure things stay interesting and to return to topics you haven't studied in a while.
Include past paper questions as often as possible, and look to maximise your results and get the best possible grade in A Level Biology by tackling topics that will yield the most marks with the least effort. Target the low-hanging fruit.
Step 3: Active Recall and Spaced Repetition
Successful revision strategies include active recall and spaced repetition. Flashcards, practice questions, and teaching the topic to somebody else are all practical approaches.
Step 4: Regularly Check Your Progress
Always test and measure your progress. After all, you may have revised for two hours, but did any of it go in?
Be sure to test yourself even after you've moved on to another topic.
Try rating your confidence on the topic and testing yourself with exam questions. This will give you a good idea of how well you know the topic and whether you overestimate or underestimate the effectiveness of your revision. An online biology tutor can help you to go over difficult concepts and assess your readiness for the exam.
The Importance of a Structured Revision Plan
As you can see, there are many topics to cover. The best approach is to develop a focused revision strategy and plan.
You must be prepared to retain complex information, understand processes, and apply your knowledge to the exam questions.
Biology exams test your application of knowledge, not just your retention of facts. You'll have to explain protein synthesis, enzyme function, and respiration. Easily done if you know it, but it's much more challenging under the pressure of an exam.
There are also data analysis and practical-based questions. For example, you may have to interpret the results from an experiment investigating enzyme activity or blood glucose concentration.
If you're struggling to revise, remember you can also search for a biology tutor on Superprof!
