Will a 3.7 GPA 1260 SATs and good extra-curricular activities get you into UW Madison?
Are you talking about transferring from another school? I've never heard of a 3.7 GPA in high school. I think those stats would get you into just about any state university in the country and many private universities and colleges in general.
MSU will not give you a minimum GPA requirement for entrance. Probably for several reasons. Primary among these is that they don't have one. The average GPA for entering freshmen in 2013 was 3.5, but those with lower GPAs are still considered. They also look at your application and essay, your SATs (ACTs for those who have them), volunteer hours and types of experience, hobbies, extracurricular activities (sports and clubs).
