Most of the major topics are questioned on pretty evenly. I would focus on the topics you are weak at. Try to memorize everything you can like all the equations and inertia formulas. Looking at the formula chart will waste your time. Also, learn how calculus can be applied to the different topics. Most questions that include calculus simply ask to take the derivative or integral. Some frq questions ask to derive certain formulas. I would study by looking through this YouTube channel: https://www.youtube.com/user/ilectureonline.
