Friendly English speaking tutor- will tutor named subjects for year 12/13 students

I'm in my first year of University, so I've just finished A levels and can relate on how much of a pain they are! However I achieved AAA in Maths, Biology and Chemistry, and I'm looking to help other students achieve these grades or even higher in each of these subjects! I'm a friendly tutor who will encourage and support you through every step- I can also provide tips and tricks that I used, which will be recent information (less than a year since I completed A levels) that not everyone will know!
