Are TESU degrees accepted for masters programs?

[jsd]

are there grad schools who are willing to accept someone who tested out of 80% of their undergrad by exam and study.com. That’s my concern with going with TESU or another one of the big 3 is that I’ll end up having to take quite a few pre-requisites anyways.

This entirely depends on the school you want to get into. Some will care, some won't. As stated earlier, Missouri State does have some specific requirements for the program you're looking at.
