UWSA 2 Step 2 CK Score Calculator
UWorld Self-Assessment 2 Step 2 CK score converter — convert your UWSA 2 raw percentages or incorrect answers into a predicted three-digit Step 2 CK score and check your passing probability instantly.
UWSA 2 is the assessment most students and advisors trust most when deciding whether to test or delay — it’s your final data point before exam day, not just another practice test.
This calculator converts your UWSA 2 wrong answer count into a predicted three-digit Step 2 CK score, using a strictly monotonic conversion model — more correct answers never lowers your predicted score.
✅ UWSA 2 typically predicts your real score within ±5–8 points when taken in your final 7–14 days of prep. The current Step 2 CK passing threshold is 218 (updated July 2025) — factor in a slight optimistic bias of 0–5 points when reading your result.
Calculate Your UWSA 2 Step 2 Score
Community-analyzed score reports put UWSA 2’s correlation with real Step 2 CK scores at roughly r = 0.85–0.90 — noticeably stronger than UWSA 1 or your raw QBank percentage. No formal peer-reviewed study exists specifically for Step 2 CK yet, so treat this as a strong estimate, not a guarantee.
Scores above 255 show a wider real-exam gap (often 10–15 points), so high scorers shouldn’t lean on one UWSA 2 result alone. Pair your UWSA 2 prediction with a recent NBME Form 13 or 14 for a far more reliable read before locking in your test date.
Frequently Asked Questions – UWSA 2 Step 2 CK
Q: What is UWorld Self-Assessment 2 Step 2 CK?
A: UWSA 2 is the second of the self-assessments provided by UWorld for the USMLE Step 2 CK. It features 160 clinical vignettes designed to simulate the format, pacing, and difficulty level of the actual exam. UWSA 2 is widely considered one of the best checkpoints to take 1-2 weeks before your test date.
Q: How does the calculator determine my predicted Step 2 CK score?
A: The conversion uses a linear model: Score = clamp(280 − 0.85 × wrong, 140, 300). It is intentionally strictly monotonic — every additional wrong answer lowers (or holds steady) your predicted score, never raises it — and is bounded to the realistic 140–300 scale.
Q: What is a passing score on the USMLE Step 2 CK?
A: The official passing threshold for the USMLE Step 2 CK is 218. However, residency matching competitive levels usually require aiming for higher targets (e.g. 240+ for core specialties, and 250+ for highly competitive fields).

The Mapping Curve: Raw Percentages to Step 2 CK Score
Step 2 CK features 160 total questions on the UWorld Self-Assessment. Getting 75% correct (which translates to 40 wrong answers) maps to roughly a 246 equivalent score under this model.
Residency Matching Target Thresholds
Unlike Step 1 which is pass/fail, Step 2 CK remains a critical differentiator in residency matching decisions. Average matched scores vary by specialty:
- Family Medicine / Pediatrics: matched average of 240-245.
- Internal Medicine / OB-GYN: matched average of 248-253.
- General Surgery / Orthopedics / Dermatology: matched average of 256-260+.
Best Practices for Taking UWSA 2 Step 2 CK
- Take it in one sitting. UWSA 2 is composed of four blocks of 40 questions. Set aside 4 hours of uninterrupted time to build endurance and test pacing.
- Complete the test at least 1 week out. This gives you adequate time to review explanations without feeling rushed before test day.
- Cross-reference with NBME Form 13 & 14. These newest forms represent the most modern test phrasing and should be used alongside UWSA 2.
