Predict Your USMLE Step 3 Score

Step 3 Score Prediction: How It Actually Works

The USMLE Step 3 exam is the final licensing step for physicians, and predicting your score requires analyzing multiple performance signals rather than relying on a single exam. Our Step 3 predictor combines Step 2 CK baseline scores, UWorld QBank performance, and CCS simulation accuracy to estimate your final score range.

Step 2 CK as Baseline: Your Step 2 CK score is the strongest predictor of Step 3 success. Most candidates scoring above 245 demonstrate extremely high pass probability on Step 3.

UWorld Performance: First-pass percentages and subject-level strengths (especially biostatistics) are weighted into our prediction model.

CCS Simulation Impact: CCS contributes about 25% of your score. Strong CCS performance significantly boosts your final predicted range.

How CCS Cases Affect Your Predicted Step 3 Score

Computer-based Case Simulations (CCS) are what make Step 3 different from every other USMLE exam — interactive patient-management cases on Day 2 that count for roughly 25% of your total score. No NBME form or UWSA grades them, which is why a multiple-choice-only prediction is incomplete.

How our model handles CCS: you enter either your average percent-correct on CCS practice cases (UWorld CCS or ccscases.com) or a simple self-rating. The model then applies a calibrated adjustment on top of your multiple-choice estimate: strong CCS performance adds roughly +6 points, while self-rated “struggled” performance subtracts about −12 points — enough to pull an otherwise-passing MCQ score below the 200 passing line.

Why CCS is an adjustment, not a matching input: in holdout testing, self-reported CCS percentages were too noisy to improve neighbor matching, so the model deliberately applies CCS as a post-hoc modifier instead of letting it distort the core prediction. That is also our honest advice for test day: aim for ~70%+ on high-yield CCS practice cases so CCS builds your buffer rather than eroding it.
