submitting AP scores to college from exams taken senior year?

AP exam scores aren’t released until July, which would be after I have graduated high school and chosen which college I’m attending. I want to make sure that I get college credit for the classes that the AP exams count towards. But how do I inform the college I end up going to of my scores from senior year? I can’t send them in with the application like I can my junior year AP scores.

You don’r send in any AP score report with your college application. You simply self report the scores on the application.
If you are taking an AP exam as a senior, use your free score report to send your scores to the college you will be attending. The college will receive your scores from all years.
