Revoking admission for a transfer student

<p>Hello!
I recently have been accepted as a transfer student to the university of michigan. I have already paid my enrollment deposit. Before accepted I was really concerned with my calculus class. I got a d+ as my midterm grade so i decided to withdraw. I tried to contact the admissions office at u of m to see if this could revoke my admission but they did not get back to me. so I withdrew from the course. Will this W be enough to result in them revoking my admission.</p>

<p>Thanks</p>

<p>Any thoughts? i'm nervous</p>

<p>dont know.. inform them of a change in schedule though</p>
