I will probably have a D my senior year but I have As in my other 4 AP classes and 4 music classes. I also have a 28 ACT and 3.98 weighted GPA. Will JMU rescind my acceptance?
Yes. Seek extra help. Hire a tutor. Do whatever needed to avoid a D, because that will put your acceptance at risk.
I say one class wouldn’t make or break you and they would understand if you got a lower grade, however you should try and get at least a high C or low B.
