Due to a scheduling conflict, I most likely will not be able to take one of my AP exams (microeconomics). Do you think the college that I intend to go to will rescind my acceptance?
No.
I called my college’s admissions office about this, and the person on the other side literally laughed at how ridiculous that would be. You’re fine! 
@OrchidBloom LOL. That happened to me too.
You will not be rescinded. Relax.
