Year 9-11 GCSE tutor, aiming to help build understanding and exam technique

Currently, I am in year 13, studying A-Levels in biology, chemistry and maths, which I am predicted 3 A*s for. My goal is to help students struggling with content or exam technique and provide study advice for their GCSEs
In my GCSEs, I achieved ten grade 9s (Maths, English Language, English Literature, biology, chemistry, physics, geography, Spanish, Chinese and RS) and one grade 7 (Classical civilisation).
I have 2 years of tutoring experience, with one of my students improving from a grade 6 to 9 in GCSE chemistry.
