In this article, I interviewed an Evangelical Christian about her experience studying at BYU:
It’s a common perception that people who choose to study at BYU either are already Mormon or become so by the time they graduate. About one percent of the student population at BYU are not members of The Church of Jesus Christ of Latter-day Saints, a number that amounted to 461 in Fall 2010, according to BYU’s official Y-Facts, which relies on student self-reporting. But that’s not how it was for recent graduate Sarah Taylor. She came to BYU as an evangelical Christian, and remains one to this day.
