I was wondering if it’s possible to decide to send all your AP scores after you submit your college application, especially for UCs. Can you decide to send none of your AP scores on the college application? Will this decision look concerning to the admissions office?
You do not need to send your official AP score report until you are admitted and enrolled into your choice college and you are not required to self-report on your application. It is your choice which if any scores you want to report.
Agreed. Sending a score report before admissions is a waste of money. You can choose to report some/all/none of your scores on the application.
The official report for college credit, if offered, is sent later. Admit consideration is different. Whether not reporting them with the app matters can depend on the major and how competitive the colleges are.
AP score reports go to the registrar.
