Replying to AP test season

Alrighty so today I took the APUSH exam and I feel fairly confident in how it went... On Monday I'm taking AP bio, and as of right now I'm not feeling extremely confident in how it's going to go. I would like some input from people who've taken it on what I should study the most, and what some previous test trends are (like majority of the test being cell cycle, evolution, genetics, etc).

Anyways, what exams are others on here taking (or have taken) this year?
