Maths is an extremely important subject, as your tutor, whether you're studying for A-Levels or your GCSEs, I would be more than happy to cover your weakest topics so that you can realise your full potential as a student. The same goes for English, with GCSEs, English and Maths are your "big two". You should aim to pass both of them. With A-Levels, I could help with Maths, and English Literature, as I got A's in both of those subjects myself.
