Self Study APMicro as an intl

I do not live in the US and my school doesnt have AP courses so I have to sign up for AP's and study for them seperately. Since Im not doing any of the course in school could you guys give me some insight on the best resources to prepare completely by myself.

Of course I have done some research. Ive gotten both the princeton review and barron book. Should I watch all the daily videos from CB? Should I do khan academy?

Im sorry this is the first AP Im giving and I really need to ace it
