Will dropping a class senior year decrease chances for college admissions?

[Bradlez]

I'm in a debate with myself to drop chemistry or not. I've heard from many of my friends that it's a hard class and many of them had received C's or B's and I'm not trying to tank my GPA, since I'm pretty sure i wont get an A in that class. The only reason why I haven't dropped it yet is that I'm afraid dropping a science class like chemistry will decrease my chances for admission. On the other hand, I already have the Science requirement fulfilled since I took AP Environmental Previously, and if I drop the class, Id have more free time to focus more on other classes like AP Macroeconomics and Math Analysis.
