UWSA 1 to Step 1: Free Pass Probability Predictor
Enter UWSA 1 as one readiness input. The calculator applies a disclosed −5 internal source adjustment and returns an experimental pass estimate with a planning range—not an official conversion.
Convert UWSA 1 to Step 1
Pick Step 1 below and enter your UWSA 1 score. Check a Free 120 result separately with the Free 120 Step 1 readiness check, and use the official CBSSA report for current Step 1 readiness guidance.

Step 1 is pass/fail. Free 120 reports only a raw percent with no official Step 1 conversion, so it is not used here. Check it with the Free 120 Step 1 readiness check, and read a CBSSA's pass probability from its official report.

Use official readiness evidence as the anchor
NBME identifies CBSSA as its Step 1 self-assessment family. The −5 adjustment and pass estimate shown here are NBMEcalc model assumptions, not an official NBME, USMLE, or UWorld conversion.

How this calculator treats UWSA 1
UWSA 1 and current NBME readiness reports are different products with different forms and reporting methods. A difference between them is not proof of a universal conversion offset.
The calculator applies an internal UWSA 1 source adjustment. This adjustment is a model assumption, not an official UWorld, NBME, or USMLE conversion and not a published validation result.
For consistency across the calculator, the current model applies a −5 point internal adjustment before aggregation. That value is versioned and may change after a reproducible validation dataset is published.
Caveat: this adjustment is an explicit model assumption, not a published claim about UWorld's scoring. Use a current official CBSSA report for readiness decisions.
UWSA 1 → Step 1 FAQs
Is UWSA 1 accurate for Step 1?+
The calculator applies an internal UWSA 1 source adjustment, but it is not an official conversion or a published validation result. Use it with the official readiness guidance from a current CBSSA.
When should I take UWSA 1?+
Use it when the result can still change your study plan. There is no universal week that fits every learner; choose timing with your school or advisor and preserve recent official readiness evidence for the decision closest to test day.
What UWSA 1 score corresponds to passing Step 1?+
There is no official one-to-one UWSA 1 conversion. Use a current CBSSA score report and its official readiness guidance as the primary signal; the calculator's pass estimate is experimental.
Should I rely on UWSA 1 alone?+
No. Combine UWSA 1 with recent official readiness evidence. The calculator accepts multiple sources and weights recent inputs higher, but its displayed range is not yet holdout-calibrated.
How does UWSA 1 differ from UWSA 2?+
The two assessments use different forms and may produce different results. This calculator models them separately, but does not claim a verified universal offset between them.
Will I pass Step 1?
Free, no signup. Add your UWSA 1 plus any NBMEs you have for a disclosed experimental estimate and planning range.
