Great question - I'm glad you're getting a head start on this.
First, have you already received the syllabus for the course? We do have a set syllabus, and you're generally going to follow it, but you're also going to prioritize based upon your strengths and weaknesses. Your teacher will talk about this on the first day of class.
In order to get a better idea of how to structure the study time you spend without your teacher (which will be most of your study time, of course), take a look at these articles:
http://www.beatthegmat.com/mba/2010/02/ ... study-planYou already have a syllabus that comes with the course, but this article still gives you an idea about all of the "moving pieces" to consider.

After you take your first practice test, read this article and do the analysis described:

Finally, if you want to continue to use the forums as a resource (and I highly recommend it!), read this article:

Good luck!
