What cles should I take senior year in high school?

I'm currently a junior in high school trying to decide what AP cles to take my senior year. I want to be a political science major at Georgetown. I'm taking three AP's right now and am getting straight A's. I will be president of two clubs next year and a member of NHS. Right now, I'm taking AP Calculus AB, AP U.S. History, and AP English 3. Next year, I REALLY don't want to take AP Calculus BC, but that might hurt my chances of getting into college. I'm definitely taking AP English 4 and AP Psychology, but should I just ditch the Calculus? Will I really need that for a POLITICAL SCIENCE major? Seriously...I was thinking about replacing AP Calculus BC with AP Spanish 4, but the Spanish 4 teacher at my school hardly prepares us for the AP test and our scores are horrible. Plus, I struggle with speaking Spanish and I am not a native speaker. I will be competing with native speakers all around the country! Please help me! O_O
