I've taken AB Calculus and just took AP Chemistry today. The free response on Calculus was really damn hard, and one of the questions I'm actually going to be sending a complaint to the College Board about because it covers material which falls under the BC Calculus curriculum. Chemistry though...wow. I had no idea what I was getting into. None of the practice tests were nearly as hard as chemistry. Chemistry also is an exercise in tedium because you get all the 75 multiple choice questions at once with no break in the middle like with Calculus.
I thought the Calc AB test was alright. Which question are you talking about?
Btw, our signatures legally mean jack shit before we are 18, so discuss discuss discuss!!!
I took the AP English Language test. Synthesis was pretty easy, although I thought it was a little dull. There wasn't really anything to talk about. The other two were fine. Sucks for my friends, who had to take the AP Art History test right afterward (they had to write a total of 12 or so essays including the APEL test).
I FUCKING HATED THE PHYSICS TEST. GAAAH. PHYSICS. CUT CUT CUT. M/C was fine but FREE RESPONSE ARRRGGGH.
(mechanics btw).
EDIT:
Anti-penny here. Did you use frigging source G?
