The student union does pretty good cheap food, and you can get jobs with the union handing out leaflets etc. Additional course costs for biosciences were mainly printing (we were told we would start with 10 print credit which we never got, had to pay for all printing - if you do a computing degree you get free printing though). Also, you have to buy a lab coat. Don't bother buying any textbooks unless compulsory, this goes for any university, any course. Either get the book out the library or just don't use it at all, journals are way better than textbooks for writing essays anyway. If you do end up buying a textbook you never use and want to sell, sell it to other students or online, not to the university bookstore, they will rip you off massively, they give you something like 15% of the original price back. Transport, I know if you need to get the bus from Talybont down to the students union they do a free bus service, there's also some free bus service that takes you to the giant Tescos and back, I've never used either of these though.
