<p>I agree, stick to people who are associated with your academic life. Advisor, professor, Dean, etc. </p>
<p>Unless that is, you go to a Christian college? If your college is very Christian and places as much emphasis on moral character as academic rigor, you might be served by getting your pastor (if he is the leader of the church) or your Christian group advisor (if they are a professor or other college staff member, NOT a student) to write something. </p>
<p>Also, make sure in your letter you present a concrete plan for getting back on track. What steps do you plan to take to improve your time management skills? What campus resources will you commit to taking advantage of? Make sure you address those in clear, concrete detail.</p>
