I feel that I owe this post to Jeff. I got my score back a few weeks ago for AUD and I'm done (with the tests and still dealing with getting certified).
AUD:
Average: 71
Trending: 99.5
Actual: 83
Total Question Attempts: 2900
Unseen Questions: 0
Time Spent: 94 hours
After about 1500 questions I kept focusing on the "missed last seen and problem questions"
REG:
Average: 68
Trending: 71.3
Actual: 75
Total Question Attempts: 2060
Unseen Questions: 561
Time Spent: 81 hours
I feel very lucky I passed REG. I was dreading another 74 or 73.
A note about the time, I would say the actual was probably 15 hours less for each as I walked away from the computer a lot.
A big thank you goes out to Jeff for setting up this testing software. It was extremely helpful and I'm very grateful it was affordable considering that I was not getting reimbursed for any of these expenses. I have and will continue to send everyone I can your way.
