Dear 100 Hour Board,
Are the three BYU schools one school with three campuses or three separate universities?
Three separate universities.
The thing is, they're all under the CES umbrella, and the brand of BYU is a valuable one, so attaching it to all three is a beneficial decision for the smaller campuses. You still have to transfer between schools like you'd transfer between other colleges. Classes are different, GEs are different, majors offered are different, purposes are different. But the branding is similar.
