<p>Directly after the admission decision. You need to do it quick because, you will need those letters of rec which can take some time to prepare/ask for, and you have to prep any supporting documents you need to send in with the packet. </p>
<p>Additionally, though I am making an assumption, I expect the earlier you send it in, the earlier you can get your response-incase there are other schools with SIR deadlines. </p>
<p>If I remember correctly, you also must send in transcripts with the appeals packet, --to update current courses, (i know frosh appeals have to do that.)</p>
<p>Don’t worry about the classes. They just want the transcripts to show what classes you are currently enrolled in. So, lets say you stack an extra pre req class that they didnt know about between november-late march, then the transcript would update that for them. They are not looking for the grades since they are not available.</p>
<p>I think the yield process has about 10% success rate for that specific year (2004?). I remember reading that file (or a similar one) months ago and they do have exact numbers on the applicants that were granted admissions, and those who were rejected…again.</p>
