I ended up doing very poorly on some of my AP exams this year. On my common app, I listed these exams as ones that I planned to take. Brown accepted me regular decision.
Would cancelling the scores be a problem?
You’re in. You’re not going to get rescinded for bad AP scores. maybe you didn’t do as poorly as you thought. If you did, oh well, whatever, you don’t get to skip some classes. Big whoop.
Thanks iwannabe_Brown. Although I’m pretty sure I got a 1 
It’s not even worth the time it would take to request a cancellation. Brown doesn’t care a whit.
Agreed. It’s not worth the time or money to pursue. Although you may end up pleasantly surprised by your scores.
