I am a first year Mech Eng student but not at UoB (not sure where that is).
Other than in the run up to formal assessment periods I am in 5 days a week. A couple of days a week it might only be for one or two 1 hour lecture/tutorial in a day, but I also go in to meet up with other students for group work or go to the library to revise together. I commute but, it is an easy one as my bus is every 20mins and only takes 30-40 mins door to uni.
