I now realize one of the reasons I was so stressed out about timing and asking questions about it (which I'd still be interested in seeing estimates on from various people) was:
On the Sybex Test Banks for both the 815 and 816 exams, the "Estimated Time" for all questions is "1 minute".
I was actually able to get a decent number of the "fact type" questions in one minute or less.
Most of the ones that contained code and various answers to confirm or rule out took me at least two. A good number took me three.
I finished the first mock 815 exam in (just) under 3 hours for the 80 questions, about 2 minutes 15 seconds each.
If you can actually do the questions in 1 minute, you are totally killing it and should ace the exam.
I think if you can do well while spending 2 minutes each you are still doing quite well.
I think averaging 2 minutes 15 seconds on a good mix of the various types of questions is still okay -- that's where I am at and I am less sure.
If someone is taking 3 minutes each on average, I think they might be in trouble and need to get faster, even if they are getting a very high percentage right.
My point here is: a 1 minute "Estimated Time", while probably the default from Sybex for anything, mostly tests that have questions like "Who won the popular vote for President in 2016?" where you either know the answer immediately or you don't...is meaningless and alarming for most test takers. I feel like the discussion in the introductory text of both books probably implies this, yet it still made me anxious in the test banks, because I know it is possible on the 819 to know almost everything and still do rather poorly if you go too slowly....
So averaging two minutes per question is better than 2 1/4 but 2 1/4 should still probably be okay, and an estimated time of "2 minutes" per question would be more appropriate to appear in the online test banks, right?
