Online physics, chemistry and maths tutor offering private after-school lessons to GCSE students

I myself recently acquired a Grade 9 in maths, physics and chemistry GCSE; I am therefore familiar with mark schemes and exam technique in addition to the subject syllabuses. Fellow students of varying abilities regularly asked me for guidance during GCSEs, which was readily given. During my time at school I was also involved in a Learning Commission, which studied retrieval methods and revision techniques.
