The vast majority of A level Maths resources out there are tailored for Edexcel or for OCR, and AQA specific textbooks are very hard to come by - so this textbook was a godsend. It explains all the little bits of the syllabus, so it is great if you're a person who wants to learn things really thoroughly. There are also oodles of past exam questions, again all from AQA, so that you know exactly the type of questions you may get. The only downside is that some of the explanations are badly worded and hard to understand - but that is only occasional, and in those cases I just supplemented my studies by using other sources.
Recommended - and got me 100/100 for both C1 and C2!
