Mechanical engineering majors in the classes of 2012 and beyond are required to complete 10 math and science (M/S) courses, totaling at least 9.5 course credits. The free elective slot may be used to complete the 10th M/S course or a technical elective may be used to complete the 10th M/S course. If a technical elective is used, it must satisfy the requirements for both a M/S and a technical elective. AP courses, such as AP Biology, may be used to satisfy a M/S requirement.
