TESU UL Math Classes

[StudentOLife]

Hey all, for those who have completed a BA Math, where do you get your Upper Level Math Classes from? 
I'm thinking of changing the Biology to Math now as I am lagging behind schedule for Biology graduation. 
Having a Math Degree would be a good option rather than just stalling on the Biology courses.

I'm done with the Comp Sci, just need to gather my math courses...
I've already got Calculus I & II from StraighterLine done
Also have the Discrete Math &  Geometry, from Study.com

Is the Coopersmith Math 301 Concepts in Math & Quantitative Analysis still UL at TESU or has that been downgraded?
I am working on the Coopersmith Math 305 Linear Algebra course right now as that is UL still with TESU.
I am looking at UL options for now as I think the lower level I have them covered already.

Currently taking Calc 3 at TESU and happy that Prof Leonard is around.  Maybe it's just me, but TESU math classes are sadly lacking.  My advisor confirmed that many of the stats classes at APUS are UL.  If you can take grad school classes, then those will come in as UL also.  Some of the coursework at Eastern University for the MSDS will likely be UL.  

How was the Discrete Math at SDC?

Contemplating Calc 3 @ TESU for GPA as well, how was your experience? Was it easy to get a good GPA out of it?
