We are in-state and I am also concerned about the size of the school, but my daughter (and husband) are fine with it. My daughter does not want to attend a small school and doesn’t really see the difference between attending a freshman lecture style class with 250 students (this is what friends at OU report) versus 350 students. She knows it will be on her to go to office hours, etc. To make me feel better (and probably herself) she is going to Fish camp and Impact. Figure the more friends she can make before the first day of school the better.
