Where to Take AP Exam

I self studied some ap courses, but my school does not allow students to take an ap exam which the student hasn’t officially taken in school. I was told that I can register through other schools that offer ap exams, but I have no idea when and where to register. I live in LA , any suggestions?

Scroll down a little bit and there’s information on how to find a test center for AP exams other than your school. https://apstudent.collegeboard.org/takingtheexam/registering-for-exams

Hope this helps :).
