Are you sure? Maybe ... but I don't know anyone with under 3.0. I would think anyone who has very poor stats already switched out of engineering.
The average grade is a B- (some C+ and B .. so they counteract), which is a 2.7, I understand. But many people take easy A GEs and other classes which should make the average engineering GPA somewhere around the B range, right?
I don't think UCLA is like Poly, where the average is in the 2s.
