There are two sections on the AP Physics C: Mechanics Exam. Section 1 is the multiple choice section while section 2 is the free response section.

Section 1: Multiple Choice Section

35 MCQ in 45 minutes


Section 2: Free Response Sectionâ€‹

3 FRQ in 45 minutes

â€‹
Timing is the main conflict when it comes to the AP Physics C: Mechanics exam. You must be extremely fluent with the topics and have practiced through dozens of problems to successfully complete the course. On AP Physics 1, students not only have much more time for the freeresponse section, but the length of the questions is much less in comparison. On the other hand, in AP Physics C: Mechanics, each FRQ will be lengthy with many parts.
Some resources can help you prepare faster than others since they come straight to the point and are designed to maximize your chance of getting a 5 on the AP exam. The book on the right was made by Ritvik Rustagi, founder of TMAS Academy.

It contains over 200 pages and hundreds of free response questions to help you prepare for the AP exam. All problems also have detailed solutions and are organized by the unit.
Guide to Preparing for the AP Exam
AP Physics C: Mechanics is a 7 unit course that involves more problemsolving compared to other courses. Please use the 1090 rule. The 1090 rule is something that TMAS Academy believes in for courses that involve problemsolving. You should allocate 10% of your time learning the theory properly, and the remaining 90% practicing. At the end of the day, physics comes down to the amount of time you dedicate to trying different, challenging problems.
For students taking this course in a proper classroom setting, make sure to listen to the teacher and follow along the course as your teacher covers the material. Taking this course in a classroom setting already puts you above students that are self studying. Some popular books used in a classroom setting include the following books below. I highly recommend students that are selfstudying the course to choose from one of the books below.
For students selfstudying, choose a textbook from the slideshow above. It's different from the review textbooks in terms of gaining depth for the content. Some students are able to prepare for the exam solely through the review textbooks, but others need to use indepth textbooks to gain a rich understanding of the topic. After you have chosen a book, make sure to pace yourself so you can finish the course on time. Try to allocate time properly for each of the 7 units so you have enough time to not only learn the theory but practice. Make sure to practice official freeresponse questions as you use that book. You can find many free response questions in TMAS Academy's AP Physics C: Mechanics book.

Receiving a free response question that only contains topics from this unit is rare. However, you can expect to use kinematics for some parts of multiple freeresponse questions.
â€‹
Make sure to pay attention to graphing all the kinematics curves. That is extremely popular on the AP Physics C: Mechanics exam.
â€‹
On the multiplechoice section, kinematics is a significantly popular topic. You will be given a word problem, and your goal will be to write an equation to represent the problem.
