The one piece of advice I can give you that hasn't already been given (at least I don't think so)

GET A JOB.

Having a job throughout uni is a lifesaver. Even if you're only working one Saturday a week, it's extra income. Student loans really don't stretch all that far. Also, it's extra socialisation. Especially if like me, you don't really hang out with your coursemates. Most importantly it's something you can add to your CV when you finish Uni, it looks good to have balanced a job while studying.
