Test missing from your student account.
For both causes listed below, please submit a ticket and include your name and school. It might take a few hours to troubleshoot.
There are two causes:
1) Usually, this results from creating a student account in the EMS for CORE or Tech Day, but your advisor somehow submitted a different spelling for the school name in the National TSA registration process. This created a new school (with new spelling) in the EMS with your affiliated account, but the account you logged into still points to your original account pre-affiliation. It is an easy fix, it just takes time. I hope you didn't wait until nearly midnight to take your test.
2) Your advisor didn't register you for the test/event.
