Most students will begin their study of mathematics with one of the two calculus sequences:
(i) Calculus: Math 161, 162, 263, and 264; the traditional sequence.
(ii) Analysis: Math 165, 166, and 267; a calculus sequence which uses a more sophisticated and rigorous approach and integrates multivariate calculus with single variable calculus.
Individuals who do not start their college mathematics with one of the above calculus sequences should take Math 105 or 110, depending on their major interests.
Careful attention should be given to the proper placement in the calculus sequence. Students having a high school calculus background should consider taking the Analysis sequence, Math 165, 166, and 267. The Analysis sequence covers approximately the same material as that contained in the standard Calculus sequence, Math 161, 162, 263 and 264. However, the Analysis sequence builds on one year of successful high school calculus and presents the material with a more rigorous conceptual approach and a significantly different order of presentation. Students who scored at least 4 on the AB or 3 on the BC Advanced Placement exams in high school should take Math 165. It is highly recommended that students begin their college calculus during the fall term of their freshman year.
Placement into Calculus II, III, or IV via AP credit is not allowed.
Credit will not be allowed for both Math 161 and 165. Moreover, credit will not be allowed for any course that is taken after the successful completion of another course for which the first course was a prerequisite.
Major Sequence in Mathematics:
A minimum of eleven course units in mathematics to include:
1) One of the calculus sequences (i) or (ii).
2) Math 200 and 215. Both Math 200 and Math 215 should be completed by the end of the second year. Students should consult with a mathematics advisor in order to determine the best time for them to take these courses.
And a minimum of six courses that satisfy the following requirements:
3) Two courses selected from Math 405, 410, 415, 425, 440, or 470. Students must take at least one 400-level course in mathematics in their senior year. Students are allowed to take more than two 400-level courses.
4) Four additional electives selected from Math 300, 307, 310, 324, 325, 330, 340, 351, 405, 410, 415, 425, 440, or approved 370/470.

A minimum of six course units in mathematics to include:
1) Math 161 and Math 162, or Math 165 and Math 166.
2) Math 263 or Math 267.
3) Math 200 or Math 215
4) Two additional courses numbered 300 or above, but excluding Math 311, 360, 397, 495, and 499.
Math 105, 106, 110, 135, 235, 397, 495, and 499 will not count towards the Mathematics major or minor.
Mathematics majors and minors who desire secondary certificates and/or middle school and area teaching endorsements should apply to the Teacher Education Program in their sophomore year.
