Allocate 45 minutes of total break time to distribute between the blocks, mimicking the pacing of the real USMLE Prometric experience. Step-by-Step Guide to Analyzing Your Results
The critical mistake many students make is assuming that an 80% raw score offline translates to a specific 3-digit number. Due to the NBME’s equating scale, an 80% on a difficult form might equal a 220, while an 80% on an easy form might equal a 240.
The NBME 9 offline score conversion formula is based on the number of correct answers (or "blocks") a student gets. The formula is as follows:
The official passing score for USMLE Step 1 is 196. This equates to getting approximately (or a 66% raw score) on NBME Form 9. The Safe Zone Buffer nbme 9 offline score conversion

Use community-driven statistical calculators (such as those found on Reddit's r/step1 or r/step2 subreddits) to input your raw data. These calculators constantly update their curves using crowdsourced student data. Limitations of Offline NBME Scores
The most accurate prediction comes from multiple data points. Track your performance across several NBME forms—both online and offline—and take the mean of your last two forms. If you use NBME 9 offline, supplement it with at least one online NBME form and a UWorld Self-Assessment (UWSA) for cross-validation. Allocate 45 minutes of total break time to
