**Choose your catalog year:**

The degree requirements given below represent recent catalog-years. Every LSU student may choose any catalog-year published during his or her time as an LSU student, and meet all the degree requirements stated in that year's catalog. Thus, new students may use a future catalog instead of the current one, and advanced students may use a past or a future catalog instead of the current one, as long as it is published during the student's career at LSU. A student cannot "mix" two different catalog years for any one curriculum.

A student enrolled in the College of Science may (a) declare a mathematics major (or other major), (b) declare or change a concentration in the math major, or (c) change the catalog-year for determining the requirements to be met for the chosen curriculum or concentration, by filling out the College of Science's "Change/Declaration of Major/Minor" form, and then hitting the "Submit" button at the bottom of that form. To declare a math minor, or if the student is currently enrolled in UCAC or UCFY or another college, the student should consult with his home college.

In case of any conflict between the rules stated here and those stated in the catalog, the catalog prevails.

**Choose degree requirements for:**

## I. Degree Requirements for Math Majors

### A. General Education Requirements and Lower-Division Non-math Requirements

The lower-division non-math requirements include the University's General Education requirements (see 2021-2022 Gen Ed requirements), but with some restrictions imposed by the College of Science (45 hrs total).

- English Composition: ENGL 1001 or 1004, and ENGL 2000 (6 hrs).
- Analytical Reasoning: Math 1550 (or 1551) and Math 1552 (or 1553) (9 hrs). (Math 1530 and Math 1540, together, cover the material of Math 1550, and can replace Math 1550.)
- Arts: Any course from the Gen Ed Arts list (3 hrs). (2021-2022 Gen Ed Arts list)
- Humanities: 3 courses (10-11 hours), chosen from the Gen Ed Humanities list. (2021-2022 Gen Ed Humanities list.) These 3 courses must be chosen as follows:
- One foreign language course. (Students whose native language is not English should check the College of Science's 2021-2022 rule on this.)
- One course numbered 2000 or above in ENGL or HNRS (3-4 hours).
- One additional course, without restriction.

- Natural Sciences: 11 hours chosen as follows:
- Either:
- a two-semester sequence in Biology chosen from the Gen Ed Natural Sciences list, plus 2 hours of Biology lab, or
- a two-semester sequence chosen from the Gen Ed Natural Sciences list in a physical science offered by a department in the College of Science (specifically, Gen Ed courses with the rubrics ASTR, CHEM, GEOL, or PHYS (but not PHSC, "Physical Science")), plus 2 hours of a corresponding lab. (See the 2021-2022 Gen Ed Natural Sciences list.) And:

- A one-semester course chosen from whichever list above (a.i or a.ii) was not used for the two-semester sequence.

- Either:
- Social Sciences: Any two courses (at least one of which is at the 2000-level) from the Gen Ed Social Sciences list (6 hrs).

(2021-2022 Gen Ed Social Sciences list.)

(Exceptions:

For the Actuarial Science Concentration, ECON 2030 is required, and counts as the required, 2000-level Gen Ed Social Science course.

For the Secondary Ed-Mathematics Concentration, EDCI 2500 is required, and counts as the required, 2000-level Gen Ed Social Science course.)

### B. Other Lower-Division Math Requirements (12-13 hours)

- Multidimensional Calculus: Math 2057 or 2058. (The 9 hours of Calculus I and II (Math 1550 or 1551, and Math 1552 or 1553) were already counted in section A.2 above.)
- Technology Lab: Math 2060.

(Exception: The Actuarial Science and the Statistics concentrations don't require Math 2060; see section C below.) - Linear Algebra: Math 2085.

(Exception: The Computational Math Concentration allows Math 2090 (plus 2 hours of free electives) to substitute for Math 2085 and Math 2065; see section C below. This substitution is also available, on petition to the Math Department, to students who must (because of another major, for example) take Math 2090.) - "Bridge courses" (6 hours):

2019-2020 and subsequent catalogs:- Select one course from Math 2020, 2025, or 2030.

(Exception: The Actuarial Science Concentration and the Secondary Ed-Math Concentration require Math 2020 only.)

A student may substitute for Math 2020, 2025, or 2030 a 3-hour-or-more math course at the 2000-level or higher that is not otherwise required, upon passing the Department’s Mathematical Maturity Exam. - All concentrations also require one, additional, 3-hour-or-more Math course at the 2000-level or higher, not otherwise required; we recommend that this course be chosen from Math 2020, 2025, or 2030.

- Select two courses from Math 2020, 2025, or 2030.

(Exception: In the 2016-2017, 2017-2018, and 2018-2019 catalogs, the Secondary Ed-Math Concentration requires Math 2020 and one of Math 2025 or 2030.)

A math major may petition the Associate Chair of the Math Department to recommend to the College of Science that a surplus, proof-intensive, 4000-level or 7000-level math course substitute for one of the required bridge courses.

- Select one course from Math 2020, 2025, or 2030.

### C. Upper Division Math (and Sometimes Non-math) Requirements: Choose a concentration

*Capstone requirement*: All concentrations listed below require a "capstone" course. Math 4019 is the required capstone course for the Secondary Education Concentration.
Math 4020 fulfills the capstone requirement for the Computational
Math Concentration; when Math 4020 is not available, a section of 4997 that has computational content may substitute for Math 4020.
Math 4020 or 4997 will fulfill the capstone requirement for the four other concentration in the math major.
For the Mathematical Statistics Concentration and for the Actuarial Science Concentration, EXST 4087 is an alternate capstone course; if EXST 4087 is not offered, EXST 4025 may be substituted for it. A student may be released from the capstone requirement by completing any departmentally approved summer REU program (see, for example, the following partial list of REU programs) and consulting with the Associate Chair for Instruction.

Students in the Actuarial Science Concentration may be released from the capstone requirement by completing a departmentally approved summer actuarial internship, or by completing the Casualty Actuarial Society Student Central Summer Program and obtaining departmental approval.

A capstone course is to be taken at the end of the student's undergraduate career, after the student has completed several 4000-level mathematics courses or during the student's final semester.

‡ EXST 4087 is a projects or advanced topics course. A minor in applied statistics (EXST) requires 18 hours in EXST (including, in addition to the above concentration requirements, also EXST 4050; and, if EXST 4087 is not offered, replace it by EXST 4025.

#### 6. Secondary Education-Mathematics Concentration (51 hours):

This concentration is part of the Geaux Teach--Math and Sciences Program. Students will obtain a degree in mathematics and, upon completing this concentration and meeting any additional requirements of the Louisiana Department of Education, will be eligible for certification in the state of Louisiana as teachers in grades 6-12.

Students interested in this concentration should obtain course advising in the Cain Center.

- Math/Science GeauxTeach courses: SCI* 2010, SCI* 2011, Math 3002, 3003, and 4019.

† PHIL 2786 last offered spring 2019; replace it with any 4000-level math course not otherwise required.

EDCI 2500 will count as the required, 2000-level General Education Social Science course.

For the 2015-2016 and prior catalogs, PHIL 2786 counts as one of the then-required social science/humanities courses.

Students should plan their course work so that the last semester of the senior year can accommodate the 12 hrs. that are required to be taken concurrently (EDCI 4006 and 3136).

In the 2016-2017 and subsequent catalogs, the Secondary Education-Mathematics Concentration requires 14 hours of free electives (unless you took Math 3002, 3003, and/or 4019 prior to 2016-2017, in which case this concentration requires 1, 2, or 3 additional hours).
