Dorothy,
We are in the same situation, but haven't received the results yet. DS8 in 4th grade - but he didn't finish the Math - so I'm worried about the scores, and if we'll have to retest. Did you have to wait 3 weeks for the results?
DS had the same testing environment - and there was a lot of entering/leaving the test room, and starting new testers, all older as well. DS asked if he could go back and re-take just the math as it was easy but he just didn't finish it.
We'll see when the results arrive.
