It just seems like TESU is making a "pre-approved" list of courses and providers (kind of a good thing). Surely Study.com, StraighterLine and Sophia will make it through (their courses are good and solid).
Like davewill pointed out, their "Starter Kit" PDF file is from November 2018. I've been asking advising about a bunch of StraighterLine and Study.com courses, to get an official confirmation that they transfer in, and have gotten responses that they transfer in, with all the ACE registry dates and everything—usually along the lines of "x course transfers in, if completed by 01/05/21."
