BIOCHEM KCL OR EDINBURGH

Hello! I desperately need help to choose between Biochemistry at KCL or University of Edinburgh ..... can anyone advice me on this? I'm not really fond of the idea of doing 4 years for degree but 2nd year entry requirement is A*AA for edinburgh which i'm not sure I can get or not.

Additionally, course content for Edinburgh is a bit broad? I read that you only specialise in Biochem in 3rd year.

However, Edinburgh has better research program than Kings and is ranked higher for biological science. Help me out pleaseee
