I got accepted to ISU, but my first semester of senior year I got 3 B's 2 C's and a D. I usually get A's and B's. If I try really hard 2nd semester and get A's and B's can they revoke my acceptance??
It is unlikely they'll revoke your acceptance because of one D. You should talk to your academic counselor, but I dont think you should be worrying too much. Once you're accepted, you're pretty much in.
I highly doubt you won't get accepted. Universities and colleges are generally out for your money, as long as you pay and get your application in on time, which you did, you should be fine.
