very different from what it was actually like. I was surprised to arrive on campus and find that there were "emo" kids, punk rock kids, black kids, asian kids, southern kids, democrats, gays, lesbians, etc etc just like everywhere else. And FWIW, in my 4 years at BYU, I've NEVER heard one kid say they thought they were better than anyone else or make any remark about them attending the Lords school as opposed to those who dont.
Most kids in Utah have no idea what attending BYU is really like.
