Major 

Biology Undergraduate Major (BS, HBS)

Print Version Print
College of Science | School of Life Sciences


Options

Ecology
Genetics
Marine Biology
Physiology and Behavior
Pre-Dentistry/Biology
Pre-Education Biology
Pre-Medicine/Biology
Pre-Veterinary Medicine

Administered by the Department of Integrative Biology under the School of Life Sciences.


Also available at OSU-Cascades campus.

The undergraduate BS degree in Biology is designed for students seeking an interdisciplinary background in the life sciences. The major couples a comprehensive biological, physical and quantitative sciences core with a variety of electives that can be catered to meet specific professional goals. Biology majors receive excellent training for graduate and professional programs.

Corvallis Campus students may choose to complete one transcript-visible option in Ecology, Genetics, Marine Biology, Pre-Dentistry/Biology, Pre-Education Biology, Pre-Medicine/Biology, or Pre-Veterinary Medicine. Options in the Biology major require fifteen or fewer additional credits (one term) beyond the basic Biology major and most students can complete the additional course work in four years.




Students in the Biology major must complete BI 211 or BI 211H, BI 212 or BI 212H, and BI 213 or BI 213H with a C– or better to continue on to upper-division Biology (BI) and Zoology (Z) course work. Students must also complete CH 231/261, CH 232/262 or CH 233/263 and CH 331 with a C– or better to continue on to upper-division Chemistry (CH) course work.

Students majoring in Biology cannot seek a dual or double major in Biochemistry and Biophysics, Biochemistry and Molecular Biology, Biohealth Sciences, Microbiology or Zoology.

The BI 197 or 198 seminar must be completed by all first-year students. The BI 298 Integrated Professional Development I: Life Sciences must be completed by all Corvallis campus students.

The major sections and courses within them are arranged in the order they are generally completed.

For further information, see MyDegrees or the Integrative Biology website at http://ib.oregonstate.edu.
