NOTE: For the third and fourth years, students should consult with departmental advisors about the appropriate 3000- and 4000-level biological sciences course requirements for their majors. All three majors require 39 total hours of biological science classes. The sample curriculum below assumes a chemistry minor. Fall
- Oral Communication Elective 3 Semester Credit Hours
- Creative Arts Elective 3 Semester Credit Hours
- Foreign Language 3 Semester Credit Hours
- Advanced BIOL Elective 3 Semester Credit Hours
- Elective 3 Semester Credit Hours
Spring
-
Advanced BIOL Electives 14 Semester Credit Hours
(Students should check with their academic advisor for complete listing of approved electives.) -
Additional elective to meet 120-hour minimum 1 Semester Credit Hours Total Hours: 120
The teacher education program includes a full year of student teaching. See Teacher Education . * Students may have to take CHEM 1301 the first semester if they do not pass the Chemistry Placement Exam. Foreign Language
A student must complete 3 hours at the sophomore level or above in a single language. The prerequisite for all sophomore language courses is credit for the freshman level. This credit can be determined through a credit by examination. The score attained on the exam will determine whether the student is placed in a second-year course, a 5-hour review course, or in some cases the first or second semester of a beginning (first-year) language course. See Arts & Sciences General Degree Requirements for further explanation. |
