I applied to med schools in 4 different cities, so I didn’t really have a problem differentiating between all the London universities or anything like that. But I think the main things you can use to help you differentiate is the type of course, whether you stand a good chance based on their entrance criteria and as just how you feel at the university (some will just feel right and some you just won’t like, go with your gut!)
