I found my first year at uni rather relaxing, I have to admit. And I think the other two years are what you make of it. I spent my first term playing games like 'British Bulldog' and so on, because apparently theatre people (I studied Theatre and Performing Arts and Media Arts) need to really get to know each other...
I spent a lot of time reading up on theatre theory, because I was the only one who hadn't studied theatre or drama before. Everybody else had taken drama A-levels or National Diploma or something like that.

Enjoy it! I wish I could do it all over again. Damn, I miss uni.
