Unfortunately planesense he is right on the money. You need very thick skin to get through (having a pair of breasts also helps, at least in the college phase), and basically be prepared to be a zombie for a year and a half (MINIMUM) on terrible money. Is it worth it in the end? Definitely. But however hard you think it will be, double it. However hard you think it will be on your personal/family life? Double it. Financially? Same again.
Whilst I don't mean to discourage you, my experience at the college was that everyone over 35 crashed and burned quite early in the piece. There's no denying that you need the speed to learn new things very very quickly. Still all the best for your testing.
