Because most of the violations we see are alcohol-related, most of our educational sanctions are tailored to that issue. We sometimes ask students to do web-based research on alcohol and other drug issues and policies. If the student agrees, we might refer them to meet with a counselor for more in-depth analysis of alcohol choices and consequences. This is explained pretty well in a link from the judicial affairs homepage. Now students who admit guilt in General District Court will have a permanent conviction on their criminal record.
Nothing changes with respect to the university judicial system.
This is really a matter for discussion between you and your student. Most judicial hearings last 30 minutes or less. Suspension-level offenses may take longer to adjudicate. You were an 'A' student in high school. I'm disappointed that you're not doing better in college.
