All students must complete a minimum of 128 credits for the bachelor's degree (or 159 credits for the five-year bioenvironmental engineering curriculum). The minimum credit requirements to satisfy areas I-VIII total 125 credits or less for at least one option in every major available at the school (with the exception of the five-year bioenvironmental engineering major). The additional 3 or more credits required for graduation may be fulfilled by any courses for which the student has met all the prerequisites. Students who have completed at least 60 credits of coursework may register for up to two of these unspecified elective courses (no more than one per semester) on a Pass/No Credit basis.
