The minor requires six courses in all:
- Two calculus courses
- Math 248 or CSC 210 (but not both)
- Three additional mathematics courses at least two of which are chosen from Math 301, 321, 322 and courses at the 400 level or above.
Certain other degree programs' requirements at Catholic University include two to four of the required six courses in the minor. Interested students in those concentrations should consider taking the additional mathematics courses needed to complete the minor.
