I only did Maths and Physics at GCSE standard and then took a year out so I had to brush up...all I used was BBC Bitesize revision site, was enough to get me into WAAC.
I don't think it's necessary to spend loads of money on study guides, use whatever resources for revision you can find on the net. It does help.
Most schools just require basic knowledge of Maths and Physics. I took an entry exam today which had some verbal reasoning, maths, logic questions and English language. Really not what I was expecting since I studied my butt off for Physics and advanced Maths
