NCLEX® CAT Exam Simulator

Authentic Computer Adaptive Testing

Master the NCLEX CAT exam before it counts. Turn on Adaptive CAT Mode to generate unique 85-150 question exams that simulate the official NCSBN scoring algorithm, building endurance, familiarity, and confidence for exam day.

Make the Real NCLEX Feel Like Practice

When the simulation feels real, the real exam will feel routine. Practice with CAT mode to experience the authentic testing environment and build the confidence you need to pass the first time.

Train Exam Endurance

Train with full-length adaptive sessions to build mental stamina, whether your exam ends at 85 questions or 150.

Practice in the Exam Interface

Experience a high-fidelity replica of the NCLEX interface and algorithm so you know what to expect on test day.

Gauge Your Readiness

Receive readiness predictions after every adaptive test to see if you're "on track" or "need improvement" before exam day.

Measure Your Preparedness Before the NCLEX Does

Turn exam anxiety into exam confidence. Experience the authentic adaptive testing format, get objective performance data that reveals your true readiness level, and focus your study time where it matters most.

Simulate the Exam Algorithm

Practice with the same Computer Adaptive Testing (CAT) scoring method as the NCLEX. Your test adapts in real-time, serving you harder or easier questions based on your previous answer to provide an accurate assessment of your readiness.

Standard scoring doesn't tell the whole story. CAT exam reports provide critical data, including your Level of Preparedness, the average difficulty level of questions you faced, and your percentile ranking compared to peers. Know exactly where you stand before exam day.

Practice Your Way

Turn off adaptive testing when you need targeted review. Switch to standard mode to focus on specific subjects or systems, build subject mastery, then return to CAT mode to test your full exam readiness.

Turn downtime into study time. Use the mobile-app to take practice tests at lunch, review performance analytics as you unwind on the couch, and continue learning anytime, anywhere.

I listened to lectures at the gym and on my way to work and took CAT tests at the beach. I succeeded thanks to UWorld!"

I studied for two weeks before my test! I listened to lectures at the gym and did many CAT tests!”

I took CAT tests all the time and that helped me to simulate the NCLEX.”

I did multiple CAT exams and readiness exams. I made flashcards and took them to the gym. Never give up on yourself!”

Do CAT exams multiple times a week! UWorld prepares your different types of questions.”

I focused on practice tests and CAT tests to get familiar with different types of questions. You got this future nurse!”

Use the study planner and CAT. When the self assessment tells you that you have a very high chance of passing, then it’s time.”

I would recommend doing at least 1,000 practice questions and taking at least 4 CAT Exams before you take the NCLEX.”

I studied at Panera and answered 200 UWorld questions each day! I also did the CAT exams and self assessments! I took the NCLEX in 30 minutes and passed in 85 questions!”

Frequently Asked Questions

Is the CAT exam NCLEX simulator included in the course?

Yes. Whether you are preparing for the RN or PN exam, our CAT NCLEX practice test modes are included in all standard UWorld subscriptions. This feature gives you unlimited access to adaptive training, ensuring you can simulate the CAT environment. By using these tools frequently, you can build the necessary testing stamina, manage anxiety, and track your consistency effectively over time before the big day.

How does the NCLEX Computerized Adaptive Test work?

Computerized Adaptive Testing (CAT) is a dynamic scoring method where the algorithm selects the next question based on your previous answer. Our NCLEX CAT simulator mirrors the official logic of the official exam:

Correct Answer: The next question selected is slightly more difficult.
Incorrect Answer: The next item becomes slightly easier.

Are UWorld’s Computer Adaptive Tests included in my 7-day free trial?

The 7-day free trial is primarily designed to give you a taste of our core study tools, including 50 free QBank questions, practice tests, and sample video lectures. However, the CAT exam simulator is a premium feature. To unlock the full power of our NCLEX adaptive practice test option, you must upgrade your account.

Is the UWorld CAT harder than the real NCLEX?

It is designed to feel just as challenging. Because NCLEX CAT algorithms target questions you have only a 50% chance of answering correctly, the exam often feels difficult regardless of your actual proficiency level.

Our computer adaptive practice testing NCLEX practice mimics this psychological pressure, ensuring you are conditioned for the difficulty of test day. If you can handle our CATs, you are well-prepared for the real thing.

How accurate are UWorld CAT predictions for the NCLEX?

Our CAT simulations are excellent for tracking your performance over time. While they do not provide a specific numerical probability score like our Self-Assessment exams, they grade you as “On Track” or “Needs Improvement.” Consistent performance on a practice NCLEX CAT exam is a strong indicator of your readiness. We generally find that students who consistently score “On Track” have a very high likelihood of passing the actual exam.

Why did my practice test shut off at 85 questions?

Just like the real NCLEX CAT exam, our simulator shuts off once it has determined your competency with 95% certainty.

Passed: If the NCLEX CAT shuts off at the minimum and you were above the passing standard.
Failed: If it shuts off and you were below the standard.

This mechanism is central to the adaptive experience, helping you understand the variable-length nature of the exam and what different stopping points mean.

Does the CAT mode include Next Gen (NGN) questions?

Yes. The real NCLEX computer adaptive testing includes Next Generation case studies, and so does ours. Our algorithm weaves NGN items seamlessly into your exam to ensure you are preparing for the current format of the NCLEX using CAT. You will encounter case studies that test clinical judgment just as you will on exam day, ensuring there are no surprises when you sit for the actual licensure test.

What is the difference between a Self-Assessment and a CAT Exam?

While both are crucial for your prep, they serve different purposes in your study plan:

Self-Assessment: A static exam that provides a predictive passing score (Low to Very High probability).
CAT Exam: An NCLEX CAT test that adapts to your answers to simulate the live testing environment.

Can I pause my CAT exam?

To maintain the integrity of the NCLEX CAT practice test, we highly recommend completing the test in one sitting. However, for study purposes, you can pause the exam if necessary. Keep in mind that on the real NCLEX CAT test, unscheduled breaks count against your total testing time. Training yourself to sit through the exam without pausing is a critical part of building the mental stamina required for success.

How many CAT practice tests should I take before the exam?

We recommend taking multiple exams to build consistency. Because CAT varies in length and difficulty, taking as many tests as you can fit into your schedule helps you get comfortable with the uncertainty. Aim to consistently score “On Track” on your NCLEX CAT practice test sessions before your exam date.
