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 also requires 16 term hours of chemistry, including CHEM 3371-72 and 3117-18; eight term hours of general physics (PHYS 1407-08); 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. A minimum grade of C­ is necessary in all advanced biological sciences courses used to fulfill the B.S. degree requirements.

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 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 CHEM 3371 and 3117. A minimum grade of C­ is necessary in all advanced biological sciences courses taken to fulfill the B.A. degree requirements.

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, 3304, 3350, and an additional advanced three- or four-hour course that includes a laboratory session. Each advanced course must be taken in residence. A minimum grade of C­ is necessary in all advanced biological science courses taken to fulfill the minor degree requirements. 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.
