Uncertain about which major I should choose in college

I don't know.

I'm stuck on these three:
Biology
Biochemistry
Molecular Biology


Can you tell me a little more about them so I can make a more informative decision.

r u planning to go to Med school? If yes, try
biology or medicine that's my opinion

I'm a molecular and cell biology major and I would strongly recommend biochemistry. Why not a biochemistry and Molecular Biology double major?
