There is a luck factor as well, luckily I was given the areas I knew and not labor and delivery. From your post it says you took Kaplan so I assume you know the assessment/implmentatation and ABC technique they teach. I found out that knowing my labs and really understanding what high and low mean paid off since I was able to eliminate some times a lab in the correct range or be suspicious of one in the bad range. Good luck, you will pass it, I know how hard it is, I failed my first time at 75 and luckily passed my 2nd attempt
