Biology B.A. | Biology B.S.

Courses are offered in ecology, genetics, and microbiology as well as cellular, developmental, environmental, and molecular biology. In addition, general coursework includes inorganic and organic chemistry and calculus, as well as courses in the humanities, social sciences, English composition, and foreign language. Students may supplement their degrees with minors or certificates in areas such as business, environmental science, animal behavior, and psychology. Outstanding students are encouraged to fulfill the requirements for an honors degree.

Many of our graduates are admitted to medical school, dental school, and graduate programs. Two-thirds of the department's graduates are available for entry-level positions. In recent years, the average GPA for all Department of Biology graduates has been 3.22, while the average GPA for Biology B.S. majors has been 3.37. Each year at least 50 departmental graduates are elected to Phi Beta Kappa.


Biology Major (B.A.) (top)

  • Full requirements for the Biology B.A. major are listed in the College of Arts and Sciences Bulletin.
  • Please use the Undergraduate Academic Bulletin that was in effect when you matriculated into Indiana University Bloomington as a degree-seeking student. The requirements outlined in the Bulletin in effect at the time of your matriculation will remain constant throughout your time in the Biology Department, assuming you graduate within eight years. Degree requirements may change significantly from year to year, so it’s very important that you refer to the correct Bulletin. If you are uncertain which Bulletin governs your undergraduate career, please consult a Biology advisor by emailing bioadv@indiana.edu, calling (812) 855-3810, or making an advising appointment with any Biology advisor.
