Students may register for a maximum of 18 units per fall or spring semester, a maximum of 8 units per six-week summer session, and maximum of 4 units in a two- or three-week intensive session (i.e., January or summer). Students may request permission to exceed this load, provided that they have at least a 3.0 GPA, no incomplete or NR grades, and adviser approval. First-year students and students with grades of incomplete and NR from previous semesters will be permitted to exceed the ordinary unit maximum only in rare circumstances. Students enrolling for more than 18 units in fall or spring will be assessed additional tuition charges (see the website of the Office of the Bursar for additional tuition and fee charges).
