Passed today with a 850. I thought for sure I was going to fail because I almost ran out of time on my 1st 3 testlets. And while waiting on the score report I was worried. It probably didn't help my nerves that over half way through the computers crashed and I had to wait 10 mins for them to get it back up. Luckily I did not lose any progress. The longest 2 hours of my life.
