Hello!
I applied for the SAT Subject Tests (Biology E/M and Math I) 3 months ago for the November administration, but decided to change the date for the Biology test just this night. Although, when I changed the date to the January administration, the November registration for Math I was no longer in my organizer. What should I do? I still have the admission ticket printed that says I’m taking both the Math I and Biology tests. Is my ticket still valid for the Math administration tomorrow?
The registration is for the date, not the test, so when you changed your registration date, you changed it for all tests. I doubt your ticket is still valid.
