GCSE chemistry, biology and physics tutoring from an A level student

I am currently an A level student studying computer science, maths and chemistry. I have achieved a grade 9/A** equivalent in computer science, maths, chemistry, biology and physics GCSE and would like to pass on the understanding of each subject I have acquired myself while studying for my exams. Alongside my experience, I am able to guide students on similar journeys as to mine to help them reach their targets!
