I had the test on the day on which the 120th hour occurred: Monday (Memorial Day!) for a Saturday flight. My test was at 2:30 PM on Monday. Received test results Wednesday AM around 12:30 AM. Uploaded everything to EHAS by 1:30 AM and went to bed. When I got up, I had received pre-approval at 4:30 AM. It actually was pretty easy, but it doesn't feel that carefree when you are waiting for your test and/or your approval.
