Paths for a degreeless but established SWE to pivot into AI research

[dfrecore]

I would say that TESU's BACS is not super rigorous, especially with math (you need Calc I, Discrete Math, and then any level math for your GE). It does have a lot more space for free electives, but since there isn't a ton of cheap alt-credit in the areas you're discussing (math specifically), I don't see how it's a better option.

If you just want a fast degree in order to go on to bigger and better things, then you should probably look for more graded credits in your area (and I'm not certain how either TESU or WGU accomplishes this for you).

I might instead look at the program you're ultimately interested in doing, and work backwards to find a program that will check all of the boxes you need checked.

I also think that your bachelor's degree doesn't have to have the rigor you want if you're going to get it in your master's program. And, you can always get the learning you want outside of a degree. In the CS/IT world, lots of courses on Coursera, edX, etc. will give you knowledge, but without a grade or college credit. As will lots of certs.
