Like if you are on the Pre-dental track, what types of classes do you take?

is taking chemistry and calculus a requirement?? I am aweful at chemistry, and anytype of math, so is it possible to take easy math courses in this case, and easy chem courses? I mean honestly, do you REALLY need to take 3 organic chemistry classes just to become a dentist, all you look at is teeth.
and is it like pre mad, where you can major in anything, as long as you are taking your predental courses? If so, then could i major in political science, and still do pre dental?
