I am slightly confused which 4 UK unit i should apply to for medicine, out of all these:
Cambridge
Imperial College
Kings College
UCL
Edinburgh
Birmingham
Bristol
Nottingham

For gcse's i got 8A*s and 3 A's, and currently I'm in year 12. Hopefully i'll get good a-levels, but I was wondering if it was worth applying for cambridge as the competition is really high.
However, I'm not sure on applying on 4 very good uni's as I don't want to be rejected by all of them.
Which 4 should i apply for and should i apply to cambridge?
