If you want the easier route, Criminology is the way to go because being a BTEC it's based on coursework and so more spread out. This is especially helpful if you don't love GCSE style exams as the testing system for BTEC is quite different. However, I take Psychology and it looks a lot better for medicine, and it's a really good subject if you work hard for it. Funnily enough I take French, Bio and Psych so we have quite similar options. Just keep in mind there's loads of case studies etc. Hope this helps a little.
