Dont commute is the best advice i can give you. 3rd, 4th and 5th year of medicine, at least from my experience, involve a lot of travel no matter where you are based. Give yourself a break in 1st and 2nd year! UKCAT isnt the hardest thing in the world if you put in a few hours, BMAT relies more on your actual knowledge, but that being said neither one of them properly distinguishes who will be a better doctor. Only go to a BMAT uni if the course suits you. You would be better placed choosing a university that has a course which genuinely appeals to you (they are all different) that is in a place you can live happily for 2 years minimum (In 3rd year plus youre gunna be travelling all the time between hospitals and GPs and everything else anyway, and you dont get as much time to sample the local delights!)
