Hmm, first of all, I am suspicious of this situation.
Do you think that you have been graded fairly? Have you earned those grades by playing too much games or partying, or is something going on that is tortious?
You know, there have been a lot of civil lawsuits filed with university defendants due to ADA discrimination for attention deficit disorder, or perhaps a lawsuit alleging poor grades based on racial discrimination, or first amendment retaliation. Grades have been used in the past as a pretextual tool to commit tortious conduct. I am really curious as to why this is happening to you....
Assuming that the grades are legitimate, I would say that you should talk to a lawyer ASAP. You should avoid Academic Probation, but keep in mind the Administrative Procedure Act, and your own state's law about the APA. You are entitled to a Notice and a Hearing (which is subject to judicial review

if they try to do anything major to you. You should try hard in school, but don't let anyone mess with you.
I am interested in this case, I am not a lawyer, but I myself have filed lawsuits against university employees for tortious conduct (i had to, being pro se is foolish, but it was that or nothing because i'm broke). I would like to help you through this as much as I can, but I would like more facts to work with.
