The highest level I took was ap calculus in high school, that combined with high sat and act math scores I never had to take a math class in college. Well, unless you count logic, which is fucking evil, at least in my college because the prof was an ultra-prick. He had some sort of vendetta against grade inflation and so graded everything so harshly and assigned so much work that the class was nigh impossible to pass. Over the years over two-thirds of students that took logic under him failed and of the roughly third of people that did pass less than 5% received an A.
