Do I have to take an AP course to take the corresponding AP Exam?
For most AP subjects, no. However, you do have to take the course before the exam for the following three AP subjects: AP Seminar, AP Research, and AP Computer Science Principles.
For all AP subjects, we strongly recommend taking the AP course before the exam if you can because it’s one of the best ways to learn the material that will be on the exam. If your school doesn’t offer a particular AP course, you may prepare for the exam on their own.
