My PEAT was 85% (retired) and 84% (practice) and I have convinced myself over the past week that I have failed. I definitely panicked during the test, and consequently, made a lot of stupid mistakes. Overall, I thought it was a very hard exam. I have counted over 25 wrong so far (from what I remember), just hoping quite a few of them were part of the 50 questions that are thrown out. Anxious to see the results!
For future test takers reading this, my advice would be not to rely so heavily on one study guide, and try to supplement that material with class notes. Also, try to remain CALM during the exam and do not let yourself get hung up on one question for too long. And when in doubt, go with your intuition and try not to over-analyze questions. I think that's mainly where I went wrong.
