That’s a pretty broad range, so you should pick your weakest areas and concentrate your review time on those
Picking Your Letters
Pay special attention to learning jargon and acronyms. The examiners will expect you to be able to identify scores of different groups of letters and understand their meaning.
One good study tactic for the NCLEX exam is simply to make a separate list of all the acronyms and specialized terminology you meet during your review and learn them like a vocabulary list. You can then use that list to test yourself on the meaning of each acronym and at the same time, write down what you know about each one.
Learn Lab Data
You should do the same with lab data. Often, you’ll be able to use the process of elimination to knock out outrageous-looking lab results offered as an answer choice, but there will likely be times when all of the answers look possible. Know what the typical results of common lab tests are and you’ll know the answer.
The exam lasts a total of five hours, and is intended to give you all the time you need to complete each question.
If you don’t know the answer, feel free to guess but don’t let yourself feel constrained by time pressures!
