When I taught on university-level business courses, my Saudi students, and my Arab Muslim students in general, cared exactly NOTHING about learning anything except possibly conversational, American-style English. To the best of my knowledge, they just pooped away their days except for spending time acquiring large amounts of consumer goods. They did very poorly yet felt entitled to good grades for no reason at all. Other Muslim students in my classes such as Pakistanis and Bosnian Muslims were often quite good students and cared about learning.

The ones that study physics and chemistry are mostly totally dedicated to their studies. Those are subjects they can readily use in their future careers as terrorist trainers.
