Science tutor for GCSE students and below

I have a grade 8 in maths, biology, chemistry and physics. I did triple science at GCSE and am studying them for A level. I would use previous exam questions each session on a certain topic to grasp how they feel about this topic and where the areas I need to cover are. I would then help them to grasp the content so that by the end of the session they can answer a similar exam question.
