Maths E.G.

When I started my chemistry degree in 2004, I was not equipped with an A-level in mathematics. But people like me are becoming rarer: as competition for places on chemistry degree courses hots up, many universities are demanding that their candidates are adept at mathematical techniques. 

Maths E.G. is a database of some 2000 maths questions, covering topics from GCSE to early degree level. The site has a nice feel, and has obviously been thought through properly. For example, most of the questions have been 'reverse engineered' to give whole number answers, according to one of the website's developers, Martin Greenhow, an applied mathematician from Brunel University.
