I have no idea if this will help you at all but I live near norwich so UEA is my closest uni and my school has links with it! Apparently, for medicine, they have a high interview rate for applicants, which means more rejections! But don't panic! The UEA loves all different types of student! On medlink there was a student there who was like 'I'm different. I worked in a sex shop' lol! So try not to worry too much. Just remember that its a uni that offers a PBL course, so they may ask you about the different types of teaching within PBL etc.
Finally, I hope u get it because norwich is pretty immense!! he he
Good luck!
