Chemistry is a cool class, but it was a hard one for me because it required a lot of math and memorization.

If you are passionate about science and good at math and memorization, I'd say take the second one, because that's what the science geeks will take.

If you aren't so great with math or memorization and just want to take the class and get the credits, I'd say take the first one, that's what all the other non-science geeks will take :P
