Day 2 postponed over tech glitch

All three of us taking Step 3 day 2 today were sent home without even starting because the testing center had a technical issue with starting the test.
Any thoughts on how to make the most of this indefinite wait period? I am legit concerned about starting to forget stuff.
I plan on doing maybe 5 or so CCS cases every morning, and a block of 30 Qs a day to keep the juices going.

Thoughts?
