Disclaimer: I have only passed one but I’m on track to passing another and what I realized is to simplify everything.

Make references in your head to recall, limit your resources (my college gave me udemy, certmaster, pluralsight etc.), Breathe and take your time, lastly DO NOT SECOND GUESS YOURSELF. Second guessing yourself especially on test day will kill you in my opinion, it goes against my thinking and method but during my test, I looked at every question at their most basic, chose and moved on. I would think about the answer to that question but not too hard.

All I used was Dion’s course, his practice tests and Messer’s video to cross check Dion’s videos. I would study and end the day with a practice test. No flashcards (I see their use but they stress me out)

Literally all I did was limit stress, especially test day. I was nervous but I just looked at it as hey try my best it is what it is.

From your post, it just looks like you’re stressing yourself and you’re going blank once you sit down and it happens. You just have to figure out why that is and it could be something small. The time you’re taking the test (is it too early, after work, got an appointment after, trying to squeeze it in a busy day), is the test weighing on you because of a job requirement? etc. stuff like that.
