Bachelor of Science Degrees

Bachelor of Science in Biology (B.S.)

The Bachelors of Science in Biology is a classic program of course surveying a wide range of disciplines, including molecular and cellular, organismal, and ecological levels of biology. The theoretical knowledge and skills taught in this program will allow students to enter graduate programs or a variety of professional careers.
Two Year Program
The two-year junior-senior BS Biology program will follow the student’s first two years after completing their AS degree in either Biology, General Science, Health Occupation, Environmental Science, Agroecology, or similar science area. Students must have degree requirements that may not have been in their AS degree: BIO 181/182, CHM151/152, CHM 235, PHY110/111; MTH 190 (pre-calculus) and MTH 213 (statistics), or MTH 191 (calculus).
Four Year BS Biology Program
This curriculum for entering freshmen includes all biology, math and science support, and general education requirements. In the summer preceding first year it is recommend a student take MTH 096 and /or 100, tested out of or passed prior to MTH 110.
