there is a 15-minute tutorial before the DAT showing you how to work the computer in terms of using the NEXT button and ITEM REVIEW...I just skipped over it because I had heard it was a waste of time, and I was ready to get started.
Also, at the Prometric center I took my test, you could leave the room WHENEVER you wanted but you had to check out and check back in and the clock would NOT be stopped on your test (so I would suggest NOT leaving).
But yea....during the break, I set up my maps for RC and some designated spaces for QR...highly suggested👍
