Some students may be able to take more than the 126-unit minimum during a four-year program, especially if they have Advanced Placement units. This permits the choice of additional free electives from such areas as biology, computer science, humanities, social sciences and other engineering courses. It also provides an opportunity to pursue a double major. The rules for combining majors in engineering and multiple majors involving other university divisions are described in the Combined Majors and/or Multiple Degrees section of the McKelvey School of Engineering Bulletin.

Traditionally, the department's undergraduate degrees have been popular with students interested in medicine because the curriculum automatically satisfies many of the pre-medical requirements. Many of the additional needed courses can be taken as electives.
