Yes, as long as there are openings, you may join us for the last part of the year, or sign up early for the coming academic year (indicate which is the case on your enrollment application).
Please note that enrollment fees are not prorated and partial school years still utilize all of the essential enrollment services -- assessment evaluation, course planning, academic advisor consultations -- so they are not discounted. There is, however, an annual "Plan Early and Save" discount offered on enrollment fees.
Enrollment for the next school year opens January 15th and closes when all available evaluation slots have been filled. Applications are not accepted during the month of December.
