So what do you guys think?

you could start by reading the admission website so that you understand how your intended major is taken into account in admissions.

Also check with your parents to be sure they are ok with paying about $60K per year to send you to a public school with its large classes, lack of personal attention and advising, etc. Remind them there is no financial aid available for OOS students.
