How Our CAT Engine Works
The same Computer Adaptive Testing algorithm used by NCSBN for the real NCLEX exam.
Start at Medium Difficulty
Your exam begins at the passing standard (0.0 logits). The first question is at medium difficulty — right at the NCSBN passing line.
Adaptive Selection
Answer correctly → next question is harder. Answer wrong → next question is easier. The engine uses Maximum Fisher Information to select the most informative question for your ability level.
95% Confidence Stopping
Once the engine is 95% confident your ability is above or below the passing standard (after minimum 85 questions, SE ≤ 0.2695), the exam stops. Maximum 150 questions.
