First, get the most current listing of requirement from the Registrar’s Office, Degree Services webpage. Look for “minor audits”.
Next, plan ahead because many classes have prerequisites that you need to complete first. You can find prerequisites on the minor audit and in the course descriptions in the Undergraduate Catalog. Contact the minor advisor for help planning.
Finally, talk to your major advisor to determine if any (or all!) of the minor classes can double count towards your major requirements.
Once you have a workable plan in place then request the addition of the minor through your MyMichiganTech webpage. Directions for how to do this are on the Registrar’s Office, Degree Services webpage.
