<p>On U of M's help page, it says the following about revoking admission:</p>
<p>"Freshmen: As an admitted freshman, the University of Michigan expects all aspects of your academic performance and conduct in your senior year to be consistent with the record you presented upon admission. Any significant decline in your academic performance, such as three or more C's, any D's, E's or F's, may be cause for revoking admission. Declining grades or a significant change in curriculum may also be cause for revoking admission. Although senior year grades are reported directly to the Office of Undergraduate Admissions and reviewed, it is your responsibility to advise OUA of any serious decline in grades or changes in course selections previously entered on your application."</p>
<p>Does that mean that I don't have to worry about any B's or less than three C's? I had a really bad case of senioritis after AP exams were over, and now I'm a bit worried. My friend who got accepted there last year ended up with a D, a C, and a few B's and didn't even get a warning, but I know that's not always the case.</p>
