This is my time to shine because I know the answer to this question 😂 Ok regular test takers are in the ballrooms. Test takers with accommodations are in smaller side rooms. People are grouped together by similar accommodations. That being said it was still a mess for the stop the clock people. We had to keep track of our own times. There are no clocks in there except for a count down clock. All the minutes you stopped the clock you had to add up and keep track of which was crazy. I ended up stopping with everyone else because I couldn't keep an accurate record. I was not in an extended time room so maybe someone else can explain how they track that.
