I have approximately 17 hours of contact a week and, being a medical student, this consists of a variety of lectures, group sessions, anatomy sessions, lab sessions, communication skills sessions and clinical visits and teaching. On top of that, I have to do a minimum of 20 hours private study, mainly working towards PBL sessions, though some of the private study is learning anatomy. The facilities for medicine are excellent, there are a lot of new facilities including a brand new, medicine specific, library and a communications skills learning centre.
There is a lot of work, I usually end up doing at least 30 hours private study, 20 is just the university suggested minimum for the course, however it's all really interesting work. There's a lot of self guided study, and when you do it is flexible, so it's easy to fit in other commitments around it, so don't be put off by the quantity of work required!
