I have a degree of engineering. Therefore, I had to take many advanced level math courses. Besides taking these math courses, I also took many engineering, chemistry, physics courses which also consisted of advanced math. Therefore, I had significant mathematics exposure in college. Besides, I also took several statistics courses.
I was also a tutor of mathematics, statistics while I was in college. In my professional jobs, being a chemist, scientist, engineer, I always use lot of math in order to calculate properties, unit conversion, etc. These calculations are much more detailed than any middle school, high school math.
