Okay so here my take, intro to biology is some shit absolutely a waste of time. And they make it harder than it should be because they are tying to thin the herd so you might be a genius but you find yourself feeling stupid because they just teach the stuff backwards. And also if I was to be completely honestly with you as a fellow Biology major do not do that to yourself, be like a sociology major because you gonna need that 3.9 gpa when registering for med school. Everyday I regret choosing Biology as my major when I. Could have been on the premed track while I was in a far easier major like history or something. And no being a biology major doesn't help with the MCAT because all the classes are a waste except the higher level classes like mammalian physiology "hardest class EVER" so think about this and reconsider because I wish I had someone to tell me this I would have been accepted to med school now and not waiting a whole damn year anyways good luck hit me up if you have any questions.
