There are two sections on the AP Calculus BC Exam. Section 1 is the multiple choice section while section 2 is the free response section. Each section also has 2 parts to them. One involves a calculator while the other doesn't.
â€‹

Section 1: Multiple Choice Question

Part A: 30 MCQ in 60 minutesâ€‹ (Calculator not allowed)

Part B: 15 MCQ in 45 minutes (Calculator allowed)

Section 2: Free Response Section

Part A: 2 FRQ in 30 minutes (Calculator allowed)â€‹

Part B: 4 FRQ in 60 minutes (Calculator not allowed)

People tend to like the free response section more due to partial credit. On a multiple choice question, if you get it wrong there's no chance of receiving partial points unlike the free response section. Many people believe that extra preparation is required for the multiple choice section. However, if you are fluent with all the topics and know how to apply them, then the multiple choice questions are simply very short free response questions with answer choice.
Some resources can help you prepare faster than others since they come straight to the point 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 250 pages and hundreds of problems to help you prepare for the AP exam. All problems also have detailed solutions, and are organized by the unit.

The videos on the TMAS Academy youtube channel can be helpful to review. They are short and come straight to the point to make preparing for these exams easier.
Guide to Preparing for the AP Exam
AP Calculus BC is a very long 10 unit course. There are two types of people that take the course, and the methods used to study should be different for each group. One group consists of students taking the course in school while the other includes students that self study the course. There's also a group of students that have done AP Calculus AB before taking this course. They will find BC to be significantly easier than others since majority of the topics on AP Calculus BC are repeated from AP Calculus AB.
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.
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 10 units so you have enough time to not only learn the theory but practice. At the end of the day, successful mathletes spend between 5 to 10% of their time learning the theory, and the rest practicing.
