Choose UWSA 1, UWSA 2, or UWSA 3
Select the exact UWorld self-assessment you took before entering your missed-question count or percent correct. UWSA 1, UWSA 2, and UWSA 3 can serve different roles depending on when you take them.
UWorld self assessment tool
Estimate Step 2 CK performance from UWSA 1, UWSA 2, or UWSA 3 using wrong answers or percent correct. Use the result alongside recent NBME scores rather than as a single exam-readiness decision.
UWSA tool
Select UWSA 1, UWSA 2, or UWSA 3, enter wrong answers or percent correct, and review your estimated Step 2 CK score range.

This UWSA score calculator is an independent educational tool and is not affiliated with UWorld, NBME, USMLE, or FSMB. Use UWSA estimates with recent NBME results, Free 120 performance, and your remaining preparation timeline.
How it works
The UWSA calculator helps students convert UWorld self-assessment performance into an estimated Step 2 CK score range.
Select the exact UWorld self-assessment you took before entering your missed-question count or percent correct. UWSA 1, UWSA 2, and UWSA 3 can serve different roles depending on when you take them.
The tool converts your UWSA input into an estimated three-digit Step 2 CK score and readiness zone. The output is a planning estimate, not an official UWorld or USMLE score report.
If your UWSA estimate is much higher than recent NBME results, interpret the lower or more recent result more conservatively. Discordant scores often point to timing, stamina, or content-mix differences.
A UWSA estimate can help decide whether to take another NBME, adjust the exam date, or focus your final review on weaker disciplines.
One high UWSA score does not erase a weak NBME trend. Likewise, one low UWSA may reflect fatigue or poor conditions. Look for repeatable performance.
The best use of a UWSA score calculator is to pair the estimate with missed-question review. Identify whether mistakes came from knowledge gaps, interpretation errors, or time pressure.
UWSA interpretation
UWSA can be useful for Step 2 CK planning, but it should be interpreted as one data point rather than a final test-day prediction.
A UWSA estimate can vary from real exam performance. Use the estimated range and your trend across multiple assessments instead of assuming the exact number will repeat on test day.
Large differences between UWSA and NBME scores deserve attention. Review test conditions, timing, and weak content areas before making a final exam decision.
If the estimate is close to the Step 2 CK passing score, treat it as borderline. A clearer buffer and a consistent NBME trend provide more confidence.
A recent UWSA or NBME under realistic timing conditions usually matters more than an older form taken before major content review.
If UWSA 2 estimates a comfortable score but your latest NBME is much lower, avoid averaging the two blindly. Review which assessment was more recent, whether both were timed, and whether the missed questions came from the same disciplines. For exam timing, the lower recent score usually deserves more weight.
A sudden low UWSA score can reflect fatigue, rushed blocks, or a weak content mix rather than a permanent drop in readiness. The useful response is to identify repeated miss patterns, restabilize timed blocks, and compare with another assessment before changing the exam date.
Supported UWSA forms
This page targets UWSA long-tail searches while keeping the score calculator directly available on the page.
| Form | Input | Best Use |
|---|---|---|
| UWSA 1 | Wrong answers or percent correct | Early or mid-preparation Step 2 CK estimate |
| UWSA 2 | Wrong answers or percent correct | Common later readiness check |
| UWSA 3 | Wrong answers or percent correct | Additional UWorld self-assessment estimate |
| UWSA plus NBME trend | Recent UWSA and NBME results | More conservative Step 2 CK readiness decision when estimates disagree |
Official references
UWSA is not an NBME product, so this page links to official USMLE and NBME sources for the score-reporting and readiness context around Step 2 CK.

UWSA FAQ
No. It is an independent educational calculator and is not affiliated with UWorld, NBME, or USMLE.
The calculator supports UWSA 1, UWSA 2, and UWSA 3.
It can provide an estimate, but it should be interpreted together with recent NBME and Free 120 performance.
Use both if possible. If they disagree, recent NBME performance is often the more conservative readiness signal.
Yes. You can enter either percent correct or wrong answers.
A safer result is one with a clear buffer above the current Step 2 CK passing score of 218, not a score close to the line.
Different question style, timing, content mix, and testing conditions can all affect performance.
No. Use your official platform report and this calculator only as supplemental planning context.
Use a UWSA 2 score calculator result as one readiness signal. It is more useful when it agrees with a recent NBME trend and was taken under realistic timed conditions.
Yes. Entering percent correct can still produce an estimated range, but the result should be interpreted with the selected UWSA form, recent NBME performance, and test-day timing in mind.
Check which assessment is newer, whether both were timed, and which one better matches your recent question-bank performance. When deciding whether to test soon, give more weight to the lower recent estimate.
