Basic calculus isn't hard, though (I get what you're saying, but still).
But I didn't have to take basic Calculus to graduate from ISU!
True Story: While I was in the Army, before I went to Iowa State, I was taking courses from the Univ. of Maryland Asian Division (UMAD) in Korea filling in the freshman requirements for this and that. So, one of the classes I took was the Math 101. My professor was a Penn State grad. So, I was accepted to ISU as a transfer student, and they accepted all of my transfer credits. However, they said my Math 101 was not hard enough and would only count as an elective. So, I had to take ISU's intro Math again for the requirement. I was like WTF? Math 101 from the Univ. of Maryland (AAU) with a professor from Penn State (AAU) and both higher ranked Universities than ISU was not good enough? So, I took it again at ISU, made the same grade and moved forward. I must say, my class at ISU was harder though in a big lecture class with an older Persian Professor instead of in the small class with UMAD. On the flip side, I was able to use Korean 101 as my communication requirement instead of Speech 101 - since I took Spanish for my foreign language requirement at Iowa State.
Still, did not have to take Calculus to graduate like they do at GT!
