Biological Sciences Course Series

Effective Fall 2023, the introductory BIO course series for majors will change such that:

BIO 11 & BIO 11L are equivalent to BIO 2 & BIO 2L, respectively
BIO 12 & BIO 12L are equivalent to BIO 1 & BIO 1L, respectively

These changes will result in course content being more modernized.  Course content for both courses will be more coordinated and will allow for a smoother transition for students.  Curriculum realignment will improve articulation with introductory courses at other institutions.

The decision charts below should assist academic advisors and students in identifying their next course(s) in the sequence.  Your academic advisor is available to assist you with determining which course is appropriate for you.  Academic advisor contact information is available at
