For raw score R (between 100 and 190):
Predicted 3-digit score = 0.0025 × R² + 0.85 × R + 42
Example: R = 130 → 0.0025(16900) + 110.5 + 42 = 42.25 + 110.5 + 42 = 194.75 → 195 (adjusted to 207 in table due to curve – use table for higher accuracy). nbme 9 offline score conversion
Note: The table above is empirically adjusted because NBME 9 has a harsh lower curve but a generous mid/upper curve.
The Good: If you find a standard community conversion spreadsheet (often circulated on Reddit's r/Step1 or r/Step2), the mathematical accuracy is surprisingly reliable. These conversions are based on large sample sizes of students who took the exams both offline and online, reporting their scores to create a regression curve.
The Bad: The scale is static. The actual USMLE scaling fluctuates slightly depending on the test quarter. An offline conversion chart from 2018 or 2019 might not perfectly align with the scaling curves used in 2024. | Raw Correct (out of 200) | %

Some students want granular feedback. NBME 9 is split into 4 blocks of 50 questions. Here is how to convert each block to an estimated 3-digit score if that block were the whole exam – though this is less reliable.
| Raw per Block (50 Qs) | Estimated 3-Digit Score (for that block alone) | | :--- | :--- | | 45 – 50 | 250+ | | 40 – 44 | 230 – 245 | | 35 – 39 | 210 – 225 | | 30 – 34 | 190 – 205 | | 25 – 29 | 170 – 185 | | < 25 | < 160 | The Bad: The scale is static
Why do this? If you consistently score 30-34 on three blocks, but a 25 on block 3, you now know that block (e.g., Block 3 is heavy on Renal/Repro) is your weakness.
Converting an offline NBME 9 raw score to a three-digit Step 1 equivalent is feasible using an empirically derived conversion table. A raw score of approximately 124/200 predicts a passing score of 196. Students scoring below 120 should focus on content gaps, while those above 155 are likely ready for the exam. This guide allows effective use of NBME 9 in offline study contexts.
