Rolling admission:Too late to apply?

<p>I'm going to apply as a Fall2012 junior transfer to UMich but I read that it is a rolling admission and people are saying that the earlier you apply the better. I was at a community college for my freshmen year and now I'm a sophomore at Purdue. While my grades at the community college were pretty good, I think my transcript for this Fall semester at Purdue will look stellar (GPA estimation: 3.85~4.0, I have a great chance of getting 4.0). So, should I wait til Janurary to send all my transcripts or should I apply as soon as possible? What about sending my online application earlier and then mail the transcripts in early Janurary, will it be too late?</p>
