I would take a year out and reapply. It depends how keen you are on Medicine I guess, but if you're keen on it then I would think it would be worth a year and then trying again. I'm at BSMS, and although I don't know exact statistics, I definitely know of at least 6 people who got no offers, took a year out, reapplied and then got in.... and it's not like I've gone round asking everybody, so I reckon the proportion must be a lot more than that!
