Biology Bio Course Numbers

Click here to return to Biology Major Requirements webpage

All Biology courses utilize a three-digit numbering system. The last digit is used to identify whether a course is a laboratory or non-laboratory course, where even numbers are non-lab and odd numbers are labs. For example, BIOL-380 is a non-lab course and BIOL-381 is a lab course.

100-level courses include our Introductory Biology courses (BIOL-181 and BIOL-191), courses for non-majors, and courses without other Biology course pre-requisites.

200-level courses are advanced Biology courses that have at a minimum one other Biology course as a requisite.

300-level courses are advanced Biology courses that have at a minimum one other Biology course as a requisite. Some 300-level courses have two required Biology courses (typically an Intro Bio course plus another advanced Bio course).

400-level courses are advanced Biology seminar courses.

When in doubt, we encourage you to reach out to a Biology professor to enquire about a particular course!
