Medical Student, can teach Biology up until A Levels and Maths up until GCSE

I am currently studying Medicine, and had gone to City of London School for boys from 13 to 18. In my GCSE's I achieved both A* in Biology and Maths. In my A Levels I achieved both A's.
I have tutored in the past, specifically GCSE students and was able to help excel their grades from the teaching methods I have learnt from my school.
