Biology and Zoology Advising Guides

The advising guides below are important tools for academic planning, but MyDegrees remains the official student checklist. Any declared majors, minors and options are tracked in MyDegrees based on the catalog year a student declares them (see catalog rights policy). Updated versions of majors and options are outlined in the new advising guides, but students will need to opt into those versions as appropriate.

Watch our video tutorial about how to use the Advising Guides for course planning.
