help

I already selected the classes that help me meet the minimum requirement to be able to apply to the schools, but since I was a Bio major, I also took many other classes that could potentially go under Bio. Would I benefit from also selecting those classes? I'm talking about classes like ecology, plant bio, physiology, etc. UCSF says "Add all relevant courses, including labs, that fulfill each requirement. ", I can't find anything on their website that says which courses can be classified under what. Am I overthinking?
