I thought this was the best place to ask this question I am an MFL specialist, looking to develop my Maths knowledge to possibly teach KS3 "/4 Maths. With a view to this, I want to take A Level Maths at night school. However, having taken my own Maths GCSE 18 years ago, I want to brush up on this first to prepare myself. Could you recommend the best course book for me to do some self-study- ideally with the answers in the back? Many thanks in advance.
