I write the following with full sincerity and wishing you well for your next attempt:
My analysis of your struggle in the exam is that you got caught in the NCEES trap and fell for the false positives on a number of problems. Many of the morning problems are designed to throw you on wrong line of thinking and reach the wrong answer included in the choices.
My advice would be - which is what I did - is to budget your time such that you can review your work. To accomplish this, I took the first 5 min of the test to read every question and label in 1-3 difficulty. 1 would be a question you can answer without any reference, 2 would be one you’ll need to look it up but know more or less where to, and 3 would be something you’d have to study and answer.
Then answer all the 1s, then 2s and finally the 3s.
This method boosts your confidence and prevents you from spending too much time on problems you’ll probably get wrong anyway even if you had an hour. Try this next time.
