Preparation for A level Maths

Hello everyone.

Whilst the GCSE maths results are not out till August, I did do a key skills level 2 on maths and got the equivalent of a GCSE grade C. (Hooray!) Though am motivated now t register onto A level maths, simply because of the challenge to try it, though it would have to be via distant learning course. (I work full time) Am doing some studying on what A level will involve before finally deciding to take up A level maths.

For those who had the experience of A level maths, passed it and such, what are the topics that need to be covered for A level and what topics should I have mastered before going to do A levels? And are there any sites that have practise papers for me to have a go on?
