Yes, I understood what you asked. However, considering you got a 5 in AP calc they won’t worry about your knowledge, which would be the case if you were taking them now with nothing else to show. So that part is OK. I know UCSB likes seeing an actual math letter grade by fall so I’m not sure how that plays out but you probably have stats, which covers that issue.
I would add into the TAU that you are taking them late because up until mid-fall you thought your AP fulfilled the calc requirement at all the UCs. Then send each UC an update of grades in mid-March through the portals.
I don’t really think it will be an issue but I’m not in the admissions office.
