Fourth semester, the final semester (6th semester in Flex) is consolidation (pre-grad clinical) so that cannot be broken up into 2 semesters. Therefore 3rd semester (5th semester in Flex) also isn’t broken up.
Yeah the website doesn’t make it clear but basically full time students take approx 5-7 classes per semester while Flex takes approx 3-4. That’s all it is. It’s meant to be Flex(ible) so less course work if that’s your preference or if that’s what your lifestyle calls for.
I’ll give an example of when I took the program full time.
January-April semester 1 (full time)-5-7classes
January-April semester 1A (flex)-3-4classes
May-August (full time)-no school
May-August semester 1B (flex)-the remaining classes you didn’t take from January-April
