A full, exam-style simulation built to look and feel like the real licensure exam, scored two ways: percent correct and a Probability of Passing.
What Your Percent Correct Means
A score is the percentage of questions correct, just like in the application. A score of roughly 65% reflects readiness to take the exam.
What Your Probability of Passing Means
A probability of passing indicates the likelihood of passing the NCLEX. If your PoP is 80%, then there is an 80% likelihood that you will pass the exam.
Why Finishing Every Category Matters
People scoring 65% or higher in our questions have gone on to pass the exam. It is important that you ensure that this percentage is based on your completion of most or all questions in every category!

Best results come after you finish at least half of each category at 65% or better, then sit the simulation. Your results break down exactly where you stand, so you can spend your last stretch of prep fixing the right things and walk in on test day feeling like yourself.
Most students have never seen the NCLEX interface before they sit down to take it for real. That's a lot of unknowns all at once. Our Simulation puts you in the exact same environment ahead of time, so you can save the nerves for something that actually deserves them.



Questions written and clinically reviewed by real nurses, built to mirror the real NCLEX format and difficulty. Adaptive technology personalizes your practice, it does not invent the medicine.

Is the NCLEX predictor simulation free?
You can create a free account and practice up to 10 questions a day with full rationales, at no cost. The full-length simulation and your Probability of Passing score are part of a premium subscription, so upgrading is what unlocks the complete NCLEX predictor. And if you finish your plan and still do not pass, the 300% guarantee means we pay you back triple.
