Part of going through the United States Medical Licensing Examination (USMLE) Step 1 exam is gathering a ton of information just related to the exam itself, outside of medical knowledge. There are countless documents on the internet that overview the timeline and test taking strategy. Some are reasonable, and some require 2 hours of sleep per night and IV fluids to get through the study plan.
Regardless of how you go about studying, being able to gauge your progress is generally an asset. For this purpose, I recommend the Clinical Review USMLE Step 1 Score Calculator, as it is one of the best Step 1 Calculator out there, but it should be taken with a grain of salt. No USMLE boards calculator is going to be able to predict your end score with pinpoint precision (or is it accuracy?). However, this is a rather comprehensive resource that can be used with a number of question banks to roughly track progress as you go through the studying process. Specifically, it uses NBME CBSSA raw scores, USMLE World 3 digit scores, USMLE World QBank Percent, Kaplan Qbank Percent, and Clinical Review Qbank Percent to generate an approximate USMLE Step 1 3-digit score with standard deviation, USMLE Step 1 2-digit score, and USMLE Step 1 percentile. Be sure to complete at least one if not several timed max-question qbank sessions for this to be meaningful. Pulling a step 1 score from an 80% on 10 USMLE World qbank questions may make you feel like a rock star, but it’s not incredibly accurate (precise?).
A small version of their calculator is below, but you can head to their site directly if you want to see it larger. To be clear though, this is not an endorsement for their other studying classes or materials, which seems to be generally unknown/unused by most medical students.
