Let myself fall way behind...

So you went more than a year since the last TECEP or course at TESU and you're still enrolled? It specifically says on the website you have to pass a TECEP, unless you're military.

I went more than a year, and it kicked me out, and I had to reapply.

If you went more than a year, that's different, you'd have to reapply after the 30 day grace period.
The per credit plan requires you to "enroll in a course or exam to extend active enrollment".
I've never gone more than a year before enrolling on a TECEP.
My enrollment date simply restarts on the 10th day, of the term in which I'm enrolled in a TECEP.
This is whether I go on to take it, drop it, pass it or fail it.

Where does it say you have to pass?

Yes I'm on the military plan, but I cannot see the statement "you have to pass" on this page Thomas Edison State University | Per Credit Tuition Plan
