Gateway to A*
I have just graduated high school achieving 3A* at A Level in Maths, Chemistry and Biology. I am currently studying Medicine at St George's University of London. Over the 2 years, I have made detailed notes on the OCR Chemistry A specification and AQA Biology specification. I ranked highly in my cohort for Chemistry and Biology (2/122 and 3/91). I hope these notes will help you in your A Level study.
