Changing to a major outside the College requires an Intra-University Transfer, and requires the student to pick up the paperwork from the College of the new major.

This means that all required courses accepted in the freshman year of any one of the College's degree programs can be transferred to any other of the College's degree programs. COOPs usually provide great work experience and often lead to summer jobs and full-time employment upon graduation. Courses in the AES curriculum are generally only taught once per year and because of the close-coupling of courses, prerequisites are strictly enforced.
