In preparation for Calc AB last year, I took 3 practice exams from a PR
book, and also had available the 2003 and 1998 released exams. On the Multiple Choice section of the exam, there was nearly not a single question that was unfamiliar to me (with the exception of 1 or 2). They always like to ask the same things. I personally think that the most intimidating ones involve the FTC, and the derivative of inverse functions. I think these are both simple concepts, but the language used in the question used to throw me off.
Also, the FRQ likes to ask similar things too. Almost surely there will be area between curves/solid of revolution question as the first question of the FRQ. Make sure to know that formula and know how to find points of intersection on your calculator. Also, the FRQ enjoys testing on concepts in calculus like if you integrate the rate of change in position (or velocity) you'll get the change in position (or displacement) Also make sure to be able to prove your statements. If you want to say that at x = 3, f(x) has a point of inflection, you must also write the reason this is is because f''(3) = 0, or f''(3) = undef.
Always be explicit, don't use pronouns. "It is increasing" is not good. Explaining "f(x) is increasing at 3<x<5 because f'(x) > 0" would probably get you some points, though.
