I got grade 9/8's in all of these subjects at GCSE, and am now studying both Chemistry and biology alevel, in this class I could help you boost your grade in any of these subject areas. I did Edexcel for chemistry and biology and AQA for RS so those doing the same exam boards would be preferred, though the content should be the same in both exam boards. I would also be able to tutor in English lit, history, maths, cooking as I received 7+ in these subjects.
