Undergraduate Program

BS in Biological Sciences

Ecology and Evolutionary Biology (BEB) Track

We require students to maintain a 2.0 grade point average (GPA) in the major, excluding allied field courses. See the advising page for information on how to declare your major, who your program advisor is, double majors, double degrees, petitioning for exceptions and more.
