Computer Science Where to Max Out Credits Before Enrolling at WGU

[diamonds]

Hello everyone!
I'm currently in the process of getting as many transfer credits before I enroll at WGU for their Computer Science BS program.

I currently have: English Comp 1, Intro to Humanities, Applied Prob and Stats, Natural Science Lab, Intro to Geo, and Integrated Physical Sciences from a B&M university.
I have taken: Intro to Communication, American Politics (Government), Calculus 1, Intro to IT, and Scripting and Programming Foundations (Intro to c++) from Straighterline.
I have also taken: Project Management from Sophia.org.

I'm considering taking study.com courses and possibly courses from saylor.
Where would everyone suggest taking the rest of the courses in order to try to max out my credits before entering into WGU?

Thanks a bunch to anyone who responds! 

*If anyone has questions about the courses from straighterline or the sophia course I took I will gladly respond*
