Does my tuition rate change once I have been admitted to the coterm program?
As long as you still have undergrad status (i.e. you have not yet graduated), you will be assessed the undergrad tuition rate for 12 quarters. Once you apply to graduate with your undergrad degree, or once you have accepted graduate financial assistance (such as an RA or TA position), you will be assessed the graduate tuition rate, and cannot return to the undergrad rate.
