She attended BYU 2 years and an Ivy league school 2 years.
According to her, her teachers were worse at the Ivy league school, most were grad students. The students she mixed with at the Ivy league school didn't strike me as particularly bright, compared to the people I knew at BYU.
You say you were disappointed in many professors at BYU - did you sign up for Honors classes? In my experience, those professors were amazing. But I'd agree that some of my BYU professors (in non-honors classes) were unimpressive.
