Took AP Calc AB on Wednesday and felt really confident about it, but I do have a funny story to share from one of the other guys: He was taking the BC exam because he felt like it (only one to do so), and his plan was to do the first multiple-choice section straight through and fill in the answers in the last ten minutes (our administrator had said he would put up a sign indicating that there were ten minutes left). About halfway through, one of the other guys asked how much time was left and the administrator said nothing, indicating that there was still plenty to spare. Well, ten minutes left rolls around and the administrator puts up the warning sign. About five minutes later, the same guy as before asks how much time is left, and the admin STILL doesn't say anything. The guy taking the BC exam, who failed to notice the warning sign being put up, hears this lack of a response and assumes that there's still a good deal of time left. Five minutes later, the admin calls time- and the guy taking the BC exam has NO ANSWERS marked in his answer booklet but almost all of them done in the workbook. He was pretty mad about that. :D
On a more relevant note, taking Biology and Physics C: Mechanics on Monday and AP Lang next Wednesday. Bio shouldn't be tough; I got a 5 on the practice exam, and I still remember most of what we covered in class during the year. Lang won't be that bad, either, although I think I'll get carpal tunnel from the essays. Physics C, on the other hand, I'm probably going to fail. I took regular Physics, and, having briefly glanced at the material that the C exam covers, I figured we had covered ~80% of it, so I decided to take the exam. Yesterday, I looked over it again and realized that we hadn't covered orbits and gravitation, angular everything (except torque), and harmonic motion; additionally, we covered almost no theory on anything besides electricity. The only other guy taking it is the same one who took the Calc BC exam, and we're both pretty confident that we're going to bomb it.
tl;dr Physics C is awful, but YOLO
