I went for the 33.3 week so I can be flexible and I don't have hassle of packing up my stuff each term. (It's a 4-5 hour train journey, and I'm lucky to of persuaded mum to drive me up for the start)
But yeah I'd be trying to get the cost down to 29.3 weeks for it if I were you.
The welcome pack is full of stuff, just working through it now and sorting into piles of varying amounts of action required. I'm sure I'll forget which pile is which.
