The Department of Mathematical Sciences offers a Bachelor of Science (BS) degree.  The BS in Mathematics allows for concentrations in Applied Mathematics, Actuarial Sciences, Secondary Education (with teacher certification in either 8-12 Mathematics or 8-12 Mathematics/Physics), and Statistics.

Registration for each course in Mathematical Sciences (with a MATH or STAT prefix) requires a minimum grade of C in all prerequisite courses.


All undergraduate Mathematics majors are required to consult with and have their enrollment approved by their undergraduate advisor before every enrollment.


Students who intend to register in the following:

MATH 0311Intermediate Algebra3
MATH 1319Math in the Modern World (C)3
MATH 1320Math for Social Sciences I (C)3
MATH 1411Calculus I4
MATH 1508Precalculus (C)5
MATH 2301Math for Social Sciences II3

must present an official document at registration showing that they have either an adequate placement examination score or received a grade of C or better in the prerequisite course. Placement exam scores expire after five (5) years.


Mathematics majors must maintain a 2.0 GPA in all MATH and STAT courses (Students should refer to the Standards of Academic Performance section of this catalog.)


All mathematics (MATH) or statistics (STAT) courses that have MATH or STAT prerequisites require a grade of C or better in the prerequisite course.
