Thinking of a Math Major

[lemma]

I have all the math classes from Sophia done. Plus, I've found calc 2 on Straighterline and 6 or 7 on Coopersmith

Gotcha. Then yeah, since math is a subject where pre-reqs, at least in the beginning, matter quite a bit, I don't see how it would be possible to accelerate faster than maybe 1.5 years-ish anywhere other than maybe TESU and SNHU. I say that because TESU/SNHU are very alt credit friendly, so they will give you credit, I assume, for those Sophia/SL courses (not sure about SNHU and Coopersmith). You probably won't get credit for those from any of the other universities I listed -- except maybe Liberty and APU? -- so you would have to actually take the courses at some college. In other words, you'd have to start from the ground up.
