What am I supposed to pack for ten weeks?

Ten weeks is about the same length as a Cambridge term. I usually survived this long with a room full of stuff, much of which was delivered by Mum's taxi at some point or other. In fact there was so much stuff that two trips were needed around graduation, and I had to return on the train.

Unfortunately this time I need to fit everything into two suitcases and a carry on bag. The hotel I'm staying in (but not paying the bills of thankfully) comes with the usual towels, shampoo etc as well as a kitchen so that's quite a lot that I won't need. Even so I still don't know where to start with what to pack.
