I just looked up their student policies and holy crap... straight from their student handbook
"
We believe that God’s ideal for sexuality is achieved when sexual
expression is limited to a man and a woman, who are husband and wife, committed in lifelong
marriage. Premarital and extramarital sexual expression and conduct are to be chaste, and
behaviors that suggest otherwise are to be avoided. Unchaste conduct is contrary to the ideals of
the University and will result in disciplinary action."

So no premarital sex, or gay sex, or else you get disciplined. Also, no alcohol,smoking, or ponography, and weekly chapel meetings. I don't think you'd really want to fake it for 4 years if you don't fit in.
