How hard is calculus in college?

<p>So I'm a biology major and I still have to take calculus. I want to take it for the upcoming quarter but I'm already taking Organic Chemistry II and Principles of genetics (Upper division class). Will I be able to handle calculus with those two classes? My professor for genetics sucks. Everybody complains about him but I have no choice, I have to take it in order to graduate on time. I don't work so I'll definitely have time, but I'm still conflicted as whether or not to take it.</p>

<p>Are you strong in math? How long ago was your last (non-stats) math course?</p>
