I am an undergraduate currently studying maths, and so have an obvious interest in the subject. There is not much up here as yet appart from an old page on sliceforms, but I plan to put up some material soon.
STEP
STEP, or sixth term examination papers, are a set of fiendish but great maths papers. I would really recommend Siklos’ booklet on the exam. for anyone at a sixth-form level with mathematical inclinations.
Other
I wrote a (humorous) statistics project, which you might enjoy reading for a laugh.
