Yes. You just didn’t officially place out of the equivalent classes.
No. Davis is very strict about this: No AP or IB credits go towards general education, even if you placed out of a class using those credits. The possible exception is that a high enough score on an AP English exam (I believe a 4 or 5 qualifies) may fulfill your lower division English composition requirement depending on your college.
Your AP credits count towards the 180 unit minimum to graduate. Given that the scores aren’t high enough to place out of the equivalent classes, and the fact that they’ve stopped including AP and IB credits in determining registration times, that’s about all you can use them for.
It’s automatically counted towards your unit total.
