Complete A-level Biology revision notes and free samples are available under the Shop tab for AQA, OCR A and Edexcel Biology A (Salters–Nuffield/SNAB).

I’m Dr Zoë Huggett, an independent online A-level Biology and Chemistry tutor with a PhD in Nutritional Sciences and a background in biosciences research. Alongside tutoring, I work part-time as a senior laboratory technician. I put a great deal of care into creating clear, specification-matched PDF notes that help students understand the course content and focus on the detail examiners expect. My resources have now been downloaded more than 7,000 times through this shop.

Each notes set is written specifically for one exam board. You are very welcome to download all three free samples if you want to compare them, but when revising, please use only the notes for your own specification. The content and required detail vary between exam boards, so using another board’s notes may cause confusion or leave gaps.

These notes are designed to support your revision, not replace active recall and past-paper practice. No single resource can guarantee a particular grade, because exam outcomes depend on many factors.
