The main purpose of Xavier's School for Gifted Youngsters (and later the Jean Grey School for Higher Learning) seems to be to teach mutants to use their powers. Does the school also teach "normal" school subjects, like mathematics, history, language arts, or science? Would a mutant at this school ever learn stuff like algebra or physics?
I'm interested in the main Marvel comics line (Earth-616, or whatever it calls itself these days), although other universes or media would be interesting supplementary information.
