Should there be Different Tuitions at Same College--More for Bio, Less for Philo

<p>So how would one charge a student who must take 12 courses to fulfill requirements for a poli sci degree and takes 4 bio courses (with labs) for a minor, plus a physics course with lab as part of the gen ed requirements, and a foreign language with lab? I count 6-7 courses with labs in this scenario.
By the same token, someone could take 12 bio courses for a major, one chemistry, one physics course all with labs, and the remaining 18 courses without labs or expensive equipment.</p>
