Taking courses at WGU not part of my degree program? And credit by examination

[Merlin]

The question I have is if I would be able to transfer graduate credits to be used in the TESU BA in math undergraduate program. I'm not sure how graduate credits transfer to undergraduate programs.

In most cases graduate credit should come just fine in an undergrad degree program. If TESU doesn't have a comparable course equivalency available, a grad-level math course will probably come in as upper-level general math credit (399/499/599). Those won't meet any of the core AoS course requirements but should be usable in the AoS electives section.

As an example, WGU evaluated my graduate-level project management and statistics course to meet the requirements of their BSCS degree.
