Cheapest way to apply/enroll at TESU

[dzaloum]

Hello, I am wondering the cheapest way to apply and enroll at TESU. My main question is:

Can I complete BOTH the application and enrollment when I buy one TECEP exam (say, the $50 one LL credit Med Terminology exam)?
Do I need to pay the $50 application fee BEFORE signing up for the TECEP?
Is there a workaround where you sign up for the TECEP as a non-matriculated student, and then switch to an enrolled student after the TECEP?

I believe I read on here somewhere that all you need to do is buy one TECEP and that's it. But now I'm reading conflicting opinions and can't find where I first saw that.

Thanks for any help you can provide
