I am going to join a Community College in 2019 fall . I had a question regarding whether AP courses would be considered by the Community College in terms of credit or by the UC or CSU I would transfer to .
You need to check with the school. In general it’s the test score that gets you the AP credit, not the class (or the grade in the class).
You need to check the four year schools you want to transfer to for their policies on AP score credit.
Your community college’s AP policy matters if you want to complete IGETC or AA-T or AS-T before transfer.
