Yes! You can take other STEM courses, Gen Ed/GEP courses, and even courses for a minor at the partner campus! If you'd like to count the course towards a Gen Ed/GEP or a minor, you must get the course pre-approved by your home campus and/or department offering the minor to ensure that it will fulfill the correct requirement.
BME students can complete a minor on the partner campus, provided that their home campus does not offer a minor with the same name. Consult with your BME Advisor to make sure you have time to complete all requirements!
