The BA/MA Program is not unlike other 'dual career' programs in which during the student's senior year they can take up to 9 credits of graduate level work while still in the Undergraduate school.
So, for billing purposes, charges would work this way for both Dylan and Liam:
For the first 120 credit hours of 'completed' course hours the students are charged as if they were an Undergraduate student. The mix of classes (Undergrad level VS Grad level) does not matter.)
This means that while under 120 hours, two scenarios can emerge:
If the total combined hours taken in a given term is between 12 and 21 hours, the student would be charged the flat rate based on their Undergraduate Admit Term:
Students entering Fall 2013
Students entering Fall 2012
Students entering before Fall 2012
If the total combined hours taken in a given term is less than 12 hours, the student would be charged the hourly undergraduate rate of $690.00
After the 120 hours of completed course hours, the student will be charged at the Graduate School per credit hour rate no matter the level of the class taken. Beginning fall 2013 that rate is $930.00 per credit hour.
