As already suggested check with the course tutor first as they may have a preference (easier if most students are using the same type of gear).
Most courses specify a DSLR as opposed to other types of camera, and Nikon or Canon are the most common choices - this helps because she'll be able to share lenses etc. with other students.
My advice given the budget is to buy an older model s/h. Buy from a dealer who gives some warranty however. CEX shops are great for s/h gear. A Canon 40D is a great choice for a student, and can be bought for around £100 leaving plenty for a couple of lenses and some accessories. I'd suggest the 18-55 'standard' zoom and the 55-200 telephoto, Not much she won't be able to do with that kit.
