Those students studying medicine are studying Med in 15th ranked medical school in the world.
14th, thank you very much!
But seriouspost:
You can aspire to the medical course and it's good that you have a goal, but don't make it a question of "feeling like a medical student", as if your self worth is going to be determined by that. That's unhealthy. Studying in a theatre also used by medical students does not change anything other than the most superficial of elements, and if that will make a serious impact on how you view your prospects etc. then you should probably do some thinking about that.
Enjoy your undergrad, don't make it seem worthless and only of value if you achieve entry into a single course.
Also the sunderland is a horrible theatre, it's freezing and the desks pull down from the front.
nb, lecture theatre allocation is a random process. the only reason that all the MD lectures are in the Sunderland this year is because everybody complained last year when they had to walk between the Spot and the Sunderland every hour. I had anatomy in the Asia Centre etc. and completely irrelevant first year subjects in the Sunderland.
