I'm currently a sophomore student in college. In my freshman year, I was under disciplinary probation . I met with the dean of students and wrote her a letter telling of my regret of what I'd done. She gave me a second chance, and since then I have depended solely upon myself, raising my GPA to a solid 3.0.
Disciplinary issues are always tricky.
First, you will need to determine if your school has a policy regarding disciplinary issues and the college application process. Many schools to not release any information regarding these issues, and colleges rarely ask questions about it, so you would not be obligated to reveal anything, and it would not have any impact. If the school will be reporting the information than you should plan on adding a letter of explanation to your application materials. Since it happended while you were a freshmen, colleges are less likely to let it influence their decisions. The severity of your actions, and the potential threat to other students, will decide how great an impact these issues will have on your admission.
