Teaching GCSE and A-Level Mathematics and/or Computer Science

I am a student going into 2nd Year of a 'Computer Science with AI' degree at University of Southampton. I got an A* in Maths at A-Level and an A in Chemistry and Computer Science. I have previous experience in tutoring however only at GCSE level although I am very capable and excited to tutor A-Level education now. As a student who just recently did his A-Levels, I know the different ways in which to learn content and which of those ways is most effective and my lessons would should you how to utilise those revision techniques to achieve the best grade possible.
