How Predictive Is UWorld QBank for Step 1?

UWorld QBank has been submitted to Predict My Step Score 98,540 times and tracked against the real Step 1 results students went on to report. In that data, UWorld QBank was a weak pass signal — barely ahead of a coin flip.

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 5% to 95%. Since Step 1 is pass/fail, there is no target number to hit: a "good" UWorld QBank score is one that sits comfortably inside the range where passing was the norm for students in our data, with enough margin that one rough block on the day would not put you at risk.

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.

Frequently asked

Is UWorld QBank accurate?

In our data UWorld QBank was a weak pass signal — barely ahead of a coin flip. No single practice test settles pass/fail on its own, though — combining your scores, weighted by each exam's track record and timing, gives a much better read than any one sitting. Predict your Step 1 score →

Does UWorld QBank overpredict or underpredict Step 1?

Step 1 is pass/fail, so there is no point bias to report. In our data UWorld QBank was a weak pass signal — barely ahead of a coin flip.

UWSA 1 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?

98,540 UWorld QBank scores have been submitted to Predict My Step Score so far. Whenever a student also reports their actual Step 1 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 1 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 →
