Barts and the London or HYMS?

I'm in the extremely fortunate position of having offers to study Medicine this year from both unis but am really struggling to choose between them. Any advice would be appreciated!

I assume you mean Barts and the London School of Medicine and Dentistry?
Rather than Queen Mary without the 's? I am really surprised you find this a struggle. Perhaps a little research on your part in the National Student Survey etc might be helpful and of course a good look at previous posts on this sight as well

Yes that's what I mean and I've change the title now. I have done a lot of research i.e read the guardian, times, NSS, posts etc. but I am still finding it difficult. HYMS has a fantastic course structure and I feel that I will learn well there. However, Barts has been an established medical school longer and its location has the added benefit of constant exposure to lots of different medical ailments. Barts is only one or two positions higher than hyms on the league tables and hyms is one or two positions higher than barts for student satisfaction...
