<p>Well those research units will still go towards your upper division units required for graduation nonetheless (other majors like mcdb will actually count those units towards your major electives). MS programs aren’t unique and I know of students who are taking graduate courses as undergraduates, with one that is actually pursuing a masters at the same time as his bachelors (the rest didn’t want to put in the extra year/s). Irregardless, ditto to everything cambridgeguy said.</p>
