What to do after being deferred by U-Mich?

<p>i received a letter from U of Michigan saying that i had been deferred. What should i do now?
there is someone saying that sending them a followup letter of interest can help, but i also hear a warning that DO NOT send them an additional letter to show how badly i am enthusiastic about UM.
UM asked me to send my fall semester grades when they become available.
SO what should i do next? just send them my grades, and that's all? or write a letter to show interests as well?</p>

<p>thanks in advance!</p>

<p>Go to the U of M forum. Lots of info on your topic due to lots of applicants in the same boat!</p>
