<p>I would need to know more about how good the students are at your son’s school. 31 is a great ACT, and the SAT is solid but not great. He is top 20% in rank – if this is at a very selective private school, then Mich should be a match and UVA /Vandertilt mild reaches. If it is a very good but not great suburban public school that sends about 5-10 graduates each year to Top 10 schools, then MI is a reach and UVA/Vanderfilt far reaches.</p>
