My buddy ran out of time and guessed on the last 10. He said the whole QR was hard. I felt it was easy and had plenty of time at the end. We both got 16's. I think there was a bad test out there that no-one could score higher than a 18 on QR because everyone who took it the same week as myself scored 18 or less. Mostly 16-17. I hope you get a much different test with the correct key. Good Luck!
