Yep, sounds like you've got your head screwed on. Although, I must point out that for kings, you need to be aiming for a UKCAT over 700 to get an interview. In addition, GEP is expensive and personally I wouldn't be wasting money on a glorified holiday to St. Lucia when there is plenty of experience available in the UK. It won't buy you extra brownie points. Finally, don't just apply to one Uni, you may as well slap some others in there too.
