Been reading through this thread and it seems a lot of people put UK medical schools on too high a pedestal compared to other countries.. There's a reason why doctors after qualification and registration in their respected countries are able to practice anywhere in the world, and thats because regardless of origin all accredited medical schools are deemed to produce graduates capable of being good physicians. If you have it in your mind that doctors trained in other countries arent as good as UK graduates then you're going to have a very bad time in the NHS, because there are a fair few doctors trained outside who work in the UK (due to the excellent healthcare system we have here) and practice without fault throughout their working lives.
Also the belief that A-levels are the be all and end all and therefore someone who gets AAA is 'intelligent' enough to warrant a place at a medical school is false, universities have only upped their grades due to the large number of applicants who have or are predicted to get AAA at A level. Even with this however they do have to weed out those not suited to the profession so this is where interviews come in. I got AAB at A-level and a first at university, I have friends who got ABC etc (e.g. not AAA) at A-level and got 1st's at uni in science degrees so your A levels are most certainly not a measure of your intelligence. Someone who doesnt meet the requirements to get into a UK medical school but is able to get a place at a medical school abroad could also be capable of being a very good doctor regardless of their A levels so dont denigrate them for their choice
