Only thing I can figure is that it prepares you for more advanced courses. I had an interesting conversation with I think it was OlympianProduct (I'll have to look now) about schools offering courses like that as electives. Thing is, had I not taken what I did, and I surely would not have if given the choice at the time, I would have never qualified for getting into engineering school and I would not have had the opportunities I've had so far in my career. Real life application though...yeah, very little for most people.
