Key advice: Be proactive during the start when determining which books you need for all your modules and hit the library asap. You have everyone on your course going for the same books. So, it's best if you get there first and get a copy. You can always extend the hand-in date as you go on during your course. Plus, buying books is not entirely necessary nowadays as majority of books can be found online. I saved myself hundreds of pounds by simply talking to people, and searching online for pdf versions of books that I needed.
