H3 Biology 2025 Notes

!!! DISCLAIMER !!! I took A Levels in 2025, so they were created for the 9816 syllabus. Additionally, this set of notes are INCOMPLETE and were personally curated for my own revision, so some topics may be explained in greater detail than others while some sections may be missing or less developed. The explanations are also written in a way that made sense to me, so they may not always match how your school or teacher teaches them. Please use these notes at your own discretion!! If there are any differences between these notes and your teacher’s notes, lectures, or official materials, listen to them. Since this was done as a google docs, I have included the link so you can also view the comments and annotations, which may provide additional context. Plus, just a tip, for H3, content is not that important in comparison to your application and evaluative skills, so it's really helpful to work on SBQ/writing practice essays then memorising content! PLEASE PLEASE do not copy, redistribute, sell, or monetise these notes. All the best for your A levels!
