FINALS. HELP.

So finals are next week and I am so stressed. I’m not so worried about my history final (I have 102% in the class), and my English final might also be OK (He’s a hard teacher, but there isn’t that much stuff on the review), but I am worried about AP Calc AB, AP Chemistry, and Physics (Online).
My calc teacher gave us a list of packets she handed out that we should use for the review, but never said anything else about the test (i.e how hard it as, if she’s curving it, how many questions, etc.)
Physics actually shouldn’t be too bad actually…
Chemistry, is the real big problem. My teacher said that a 78% percent on the test is a guaranteed 5 on the AP exam… NOT GOOD. I DON’T WANT A 78%! Luckily for us though, if we do all of the review packets, we can get an extra 18% on it. I am fine with a B on it, but that means I need at least a 62% for a B-, which seems difficult since she says a lot of people get 40%'s.

So how should I approach studying these. My district does 3 separate days for testing, 2 tests each day. History and band are the first day, easy. The second day is English and Math, which is sort of difficult. Third day is Physics and chemistry, but if I finish my Physics exam before the exam date then I can study for chemistry all hour.

So, knowing this, how should I begin to study for these exams?

Are there curves?

On chemistry there is an 18% curve if I do the midterm review but I’m not sure about any other class.

I honestly wouldn’t worry. Its high school. Just do your best and do a little bit of studying, but don’t stress yourself out too much. I took AP calculus 1 and 2 my Junior and Senior year in high school and got A’s and B’s. Then on my AP Exam I got a 1 lolol.
