Withdrawing from TECEP / Enrollment

[Seagull]

I let mine laspe without taking the exam and didn't ask for any refund.  It served my purpose to be enrolled to get upper level courses added from sdc, and others.  I wasn't ready to take sos110 right away because I was finishing UL elsewhere. I thought of it as an extra fee for that advantage to me and trimmed budget in other areas for a few weeks.

Cool.

If I attempt the exam and do not pass it won't affect my GPA, I believe, so might as well attempt it.
My main reason is to preserve the catalog for one more year.
I may find use for that course transferring it to COSC.

From my understanding, the application expires every three years but enrollment is yearly and the catalog follows the enrollment time. Correct?
