How Predictive Is UWorld QBank for Step 3?
UWorld QBank has been submitted to Predict My Step Score 17,268 times and tracked against the real Step 3 results students went on to report. In that data, UWorld QBank showed moderate predictive power: a clear link to the real score, with plenty of individual variation.
What is UWorld QBank?
A question-bank percentage is your cumulative percent correct across a QBank (UWorld or AMBOSS). It reflects learning over the whole study period — first pass, second pass, timed and untimed modes mixed together — rather than a single timed sitting, so it behaves quite differently from a self-assessment and depends heavily on how you used the bank.
What is a good UWorld QBank score?
In our data, UWorld QBank scores ranged from 20% to 94%. The link is real but loose: two students with the same UWorld QBank score can finish well apart on the real exam. A "good" UWorld QBank score is one that puts your likely outcome comfortably above the score you need — run it through the predictor to see where you stand.
When should you take UWorld QBank?
A QBank percentage is not something you "take" — it accumulates. It is most meaningful once you have finished a full pass of the bank, and it says more about how you studied than about a single test day.
Does it matter when you take UWorld QBank?
Timing matters twice over. First, a score from six weeks out is a snapshot of a student who then kept studying, so early tests tend to sit below the real result — much of what looks like "underprediction" is simply improvement after the test. Second, our predictor does not treat every score you enter equally: each one is weighted by the exam's R² and by how recently you took it, with a recency factor that decays exponentially from your most recent test back to your oldest, and your three most recent scores drive the final adjustment. Enter the days-before-exam for each test honestly — it changes the answer.

Some Step 3 practice tests miss your real score by 20+ points, and one NBME form barely tracks it at all. Don't find out which on exam day.

Is UWorld QBank accurate?
UWorld QBank showed moderate predictive power in our data: a clear link to the real score, with plenty of individual variation. But no practice test is "accurate" on its own — most are taken while you are still improving, so the number you see is rarely the number you get. Combining your scores, weighted by each exam's track record and timing, gives a sharper answer than any single test. Predict your Step 3 score →
Does UWorld QBank overpredict or underpredict Step 3?
UWorld QBank is reported as a percentage rather than a 3-digit score, so there is no direct over/under-prediction figure. Its overall predictive power in our data is moderate.
Is UWorld QBank or UWSA 2 more predictive?
UWSA 2 is more predictive in our data. The exact gap is part of the full ranking, which is available to premium users.
Where does this data come from?
17,268 UWorld QBank scores have been submitted to Predict My Step Score so far. Whenever a student also reports their actual Step 3 result, the pair goes into the model behind this page; it was last refit on 2026-05-14.
Can't I just ask ChatGPT how predictive UWorld QBank is?
Not reliably. A prediction is only as good as the paired data behind it: real UWorld QBank scores matched to the real Step 3 result those same students went on to get. General-purpose AI models are trained on forum posts and articles, not on verified outcomes, so what you get back is a summary of anecdotes rather than a calibrated estimate. The numbers on this page come from students who reported both. Read more →
UWorld QBank alone gives you a blurry answer. Your full set of scores gives a sharp one.
The predictor combines every practice exam you have taken — weighted by how predictive each one is and how recently you took it — into a single prediction with a 95% confidence interval.
