Money things I did not know as a student that I now hand down to new students:
1) There are bursaries for bloody everything. I was eligible for a load, just assumed that I wouldn't be as I was an averagey student from an averagey family. Check it out
2) Most universities keep a team of student staff- normally called ambassadors or similiar- as casual workers for their recruitment team. Basically these guys do the running around for school visits, open days etc, envelope stuffing for mailshots... Why is this good? Well because 1) it pays for easy work and 2) there are usually about 3 girls to every guy. Really I don't know why we pay the guys.
3) Don't buy the reading list on day one, there will be at least one book you never open, wait til you actually have some reading to do. ALso check out used book sales, ebay etc. Oh and this is more specific but check the authors to see if any of the books were written by the husband/wife of the lecturer!
