<p>I’m confused. As of the classes, easy vs. hard, that shouldn’t be a factor. Bio 93, I think it was, was one of the first classes too that you have to take, and it’s one of the harder ones almost meant to weed out people who aren’t really into the major. There are a lot of other attempts too, so yeah, if you do love Biology, stick in there, and grades shouldn’t matter all that much as you will get better as long as you stay there and also, you do have to factor in the department trying to weed as much people out as possible by not giving them as high grades as they would have liked.</p>
