Requirements for the B.S. Degree. This degree program is designed for students who plan careers in the biological sciences or further study in graduate or professional schools. A candidate for the B.S. degree must complete a minimum of 10 courses in biological sciences, including 1401 and 1402 and eight additional courses that: 1) total at least 26 advanced term hours, 2) include at least one course at the 4000 or 5000 level, and 3) include at least two courses with laboratories.
The B.S. degree requires 16 term hours of chemistry, including Organic Chemistry I and II, with labs; eight term hours of general physics ; MATH 1337; and one additional course chosen from MATH 1338, STAT 2331 and STAT 5371. Although statistics is used extensively in biological research, preprofessional students should be aware that certain medical schools require a full year of calculus.
Requirements for the B.S.-M.S Degree. This degree program is designed for students with a strong interest in a research career. It is a five-year plan that results in both the B.S. and M.S. degrees. Admission into the program is by petition and occurs during the spring term of the second year. A research mentor must be identified and a minimum 3.2 G.P.A. in science courses is required. The Department Graduate Committee will evaluate interested applicants. Tuition support is provided in the fifth year, and stipend support is provided for summer research and throughout the fifth year. Students in the program must be engaged in research year round and will enroll in BIOL 2101 and 2102 in the third year.
All of the B.S. Degree requirements must be completed and include the following courses: BIOL 3304, 3350, 3398, 3399, 5304, 5310, 5311, 5110. The requirements for the M.S. degree will be met in years four and five. During year four, students will complete BIOL 6121, 6122, 6310 and 6322. During year five students will typically complete BIOL 6123, 6124, two additional graduate courses and sufficient research credits to total 15 credit hours in each term of the fifth year. To remain in the program, students will maintain a 3.0 G.P.A. in science courses and exhibit satisfactory progress in their lab work.
The Departmental Distinction Program. A biological sciences major with sufficiently high academic standing may graduate with departmental distinction by successfully completing a special program of study that includes independent reading and research and a senior thesis under the direction of a member of the departmental faculty. To graduate with departmental distinction, a student must be working toward the degree of Bachelor of Science and must submit an application to the Undergraduate Studies Committee of the department for this designation during the first term of the junior year. At the time of the application, the student must have completed at least 14 hours of biological sciences, including at least six advanced hours, with a G.P.A. in these courses of at least 3.50 and an overall G.P.A. of at least 3.50.
For students who have transferred to SMU, two grade point averages will be calculated, that for all work attempted, and that for work completed at SMU. Admission to the program will be based on the lower of the two averages. With departmental approval, the student will enroll for BIOL 4398 in the second term of the junior year. Upon completion of this course with a grade of B+ or better, the student will enroll during the senior year for BIOL 4399 in which a research project will be carried out and a senior thesis written and presented to the faculty. Performance in these courses and maintenance of a 3.50 G.P.A. for all biological sciences courses attempted will determine if the B.S. degree will be awarded “with departmental distinction.”
Requirements for the B.A. Degree. This degree program is designed for students who wish to couple training in the biological sciences with a broad liberal arts program. Students who are preparing for medical or dental school should consult with the Premed adviser about additional science requirements. A candidate for the B.A. degree must complete a minimum of eight courses in biological sciences, including 1401 and 1402 and six courses that: 1) total at least 18 advanced term hours, 2) include at least one course at the 4000 or 5000 level, and 3) include at least two courses with laboratories. The B.A. degree also requires 12 term hours of chemistry, including Organic Chemistry I, with lab.
Requirements for the B.A. Degree with Teacher Certification. Students interested in the B.A. degree program with teacher certification in secondary education should confer with the Teacher Certification representative in the department to plan a specific program of study.
Requirements for the Minor. Students majoring in other departments may obtain a minor in Biological Sciences by completing BIOL 1401, 1402, and at least nine advanced credit hours, which must include BIOL 3304, 3350 and an advanced laboratory course. Each advanced course must be taken in residence. CHEM 1303, 1304, 1113 and 1114 also are required for the minor. A student may not earn minors in both Biology and the Natural Sciences.
The courses outlined in this section are designed to satisfy the curricular requirements of nonscience students. BIOL 1303 is not open to students who have earned prior credit in BIOL 1401; and BIOL 1304, 1305, 1308 and 1310 are not open to students who have earned prior credit in BIOL 1402. Nonscience majors should note that BIOL 1401 and 1402 may also be taken to satisfy distribution requirements.
