If you are already accepted into a school, do 2nd quarter grades/midyear report matter?

I think my grades are going to be worst this 2nd quarter because of midterms but I was accepted into the university at buffalo. Will the college do anything? Do I have to send in my midyear report? Thanks.

Almost all colleges want a mid-year and year end report. They want to be sure you didn’t drop classes you said you were taking, and that your grades are respectable. It takes a pretty big dip in grades to get an acceptance rescinded, but it does happen.
