OP, probably the most important stat that you should look at is admission rate. If you are looking at a school with an admission rate of only 10-15%, there is a very good chance that you will be rejected even if your GPA and ACT score place you above the median GPA and ACT numbers for the school. Also, keep in mind that a lot of kids with somewhat lower GPA/ACT numbers will get into a school because they have a hook (recruited athlete, legacy etc …). Thus, an unhooked kid might need to be at around the 75% mark to have a legitimate shot.
