How many courses can I expect to complete in a session?

[HogwartsSchool]

Hi! I'm starting UMPI tomorrow and am wondering what to expect when it comes to course length and difficulty. I'll be doing the BA in History and Political Science with the History concentration. For background, last month I graduated with my BSBA from WGU in Management. I was able to finish that program in about 4.5 months, completing 96 credits. I just wanted to ask if I could expect a similar rate of acceleration with UMPI. As it stands, I have 13 courses to complete in the program. I believe I am familiar with most of the class material (based on the course descriptions at least) and will be able to spend as much time on the program as I need to, as right now I'm a full time student. Would it be reasonable to plan to complete the degree in one session? Thanks! 

If you don't mind me asking, why are you doing a UMPI BA in History and Political Science after completing a WGU BSBA degree?

btw: I am not judging because I am starting my second bachelors tomorrow, for me, its about licensing.
