in some schools if they are below full time, they lose housing as well. My D17 got very sick at the beginning of the semester and had to drop one class, and now is at the minimum to be full time. When talking to the school about potentially having to drop another class we were told she would then lose her housing. the classes could be curved, and worse case, he would have to repeat one of the classes if he failed. Many kids have a rough first semester, and then settle down the rest of their college careers.
