Biology tutor age ranges 11 to 18 from GCSE prep to A-Level

I have achieved A* across all of my A-Levels (Biology, Chemistry, Maths and an EPQ). I know from a students perspective what methods work best in understanding complex topics and achieving top marks in an exam. I have tutors friends and colleagues in the past whom went from getting Ds in biology to As. I also made a successful application to study medicine at oxford university and currently in my second year. I can provide help in understanding the application process for university.
