AP Chemistry, AP Calculas BC, AP Statistics, how hard are they?

[Ashana]

I am taking these three next year (senior year of highschool...yay cant wait for college...-.-....). I am of course going to study like hell over the summer because I know that getting a 5 on the AP calc BC exam means a full year exemption of college mathematics (requirements for graduation from certain colleges...i think). I am taking AP statistics because I heard the maximum level of mathematics it uses is algebra two...so I was hoping that would be easy. And AP chemistry.....I took normal chem and got an A but I heard the AP exam is veryyy difficult. I know many people that have A's and B's in AP chem. So can you please tell me how rigorous each course is(well i know its AP so its hard but i would like to know how hard they are compared with each other. I am in AP biology right now and damn...its impossible to not fall asleep during the 2 periods of notes). thx in advanced
