I am out of school now and reapplying to university for 2015 entry, to help me with my reapplication I decided to try and get an A Level in Further Maths. AQA have some textbooks for FP2, FP3 and FP4 but they don't seem that good. I need a book/books that will help me learn FP1, FP3, FP4, M3, D1, and D2. Any recommendations?
