How does the residency wavier free work?

The TECEPs are treated like normal classes in the sense that the registration period occurs way before the actual class/test. So if your enrollment is up in Jan, you'd want to actually TAKE a TECEP that occurs in December. But to do that, the registration would be in October

It's not as bad as that. The regular registration deadline for Dec 2019 term is Nov 17, late registration deadline is Nov 24. In addition, there is a grace period, so if your enrollment is up in Jan 2020, being signed up for the Jan term (deadline Dec 15) will work. That said, I could understand not wanting to depend on a grace period and getting it in Dec. If someone is concerned, this is one of those times where it might actually make sense to call advising and have them tell you which term you need to be in and have them go ahead and handle the registration.
