If you want med school take all of the premed classes (that usually includes calculus and physics).
If you do not care too much about money study what interests you.
If you want Law School, you do not have to study poli sci, I do not know where this notion of "pre law" majors originated. Law school students come from every background, the top LSAT scoring majors are consistently physics, philosophy and economics. Law schools, unlike med schools, have no mandated undergrad courses for admission, almost everything is about your LSAT score.
Finally, if you do not like school but want to make a good living do not go to college. Learn a valuable trade, seriously, there is no shame in being a certified and professional plumber. They only allow civilization to exist, whereas civilization could exist and without the tens of thousands of "_______-studies" majors.
