I think your claim that "calculus was a university requirement" doesn't align with what I'm reading in their degree requirements, which is "MA and CS: Mathematical Studies (combined six credit hours)"
> This core area has two categories. Mathematics (MA) is the acquisition of essential skills in basic mathematics. Computer/statistics/quantitative applications (CS) applies mathematical reasoning and requires students to complete a course in either the use of statistics and quantitative analysis or the use of a computer to assist in serious analytical math work.
> This requirement has two parts: At least three credit hours must be selected from courses designated MA and at least three credit hours must be selected from courses designated CS, and all students are expected to fulfill the MA requirement by the time they accumulate 30 credit hours in residence at ASU.
Sounds like you could take calculus to satisfy the Math requirement, but you could decide to do other Maths instead?
