<p>Alexandre, I live in Michigan and I have visited UMichigan many times so I know what I’m talking about. Michigan has more GSIs to fill in large introductory courses than Northwestern. Northwestern has the same opportunities like UMichigan, just that the student population is smaller. At UMichigan, undergraduate opportunities are very competitive (reserved for the best potential). I have the opportunity to speak with my professors on a daily/weekly basis that I wouldn’t have at UMichigan. I also have the opportunity to work on research projects here at NU that I probably would have not done at UMichigan because many students would want the same thing. Professors at very large research universities have greater preference for their grad students than undergrad students. UMichigan, other than academics, just did not fit my personality (small classes, close interaction with the professors, caring professors, etc.)</p>
