Hi everyone:)) Here are my CIE A2 level Biology topic notes for the syllabus. These notes are tailored to the A level syllabus as well as the mark scheme as if you do enough past paper questions you will see a recurring pattern with the types of questions asked about each topic. My notes include summaries, labelled diagrams, and step-by-step explanations to difficult mechanisms such as how ADH and the lac operon works. Please keep in mind my notes are handwritten! These documents as well as other revision material eg. past papers and anki helped me to achieve an A* for A level Biology so I would recommend using these notes alongside other revision material as it may save you some time. Lastly, I just wanted to say GOODLUCK!! This is a very challenging and content packed course so I understand the stress you may be feeling. Feel free to message me anytime if you have any questions regarding my notes or even for advice on A level biology:))
