ucla has one too. you take a year off after 2nd year to the anderson business school and finish the program and come back to finish your latter 2 years. whether you could still cut an ideal prep after that year off is a very good question.
we have combined degree with mph, ms, phd as well.
tuition for dds/ms is covered while dds/phd will get a stipend after 2nd year.
obviously, it is a separate application and u need to take gre, gmat, lsat, etc. If you could get into a professional sch, i m sure getting into another department is not that hard.
