Enrollment in TESU

[dfrecore]

Since you've applied to TESU, you don't need to enroll in anything. You have roughly 6 months before you need to.
My suggestion is to finish your SL courses first (all of them), transfer those credits to TESU.
Take your Study.com courses and call TESU to get the "partnership pricing", finish the Study.com courses
Take the final capstone course at TESU and you're done with the degree!

I personally would not do this. 6 months could EASILY go by without you even realizing it, and then you'd be back to square 1 or worse, they could change the requirements on you.

I say take a TECEP sooner rather than later, and change to the Study.com affiliate membership while you're at it.
