The Free 120 is the official Step 1 practice exam released by the NBME. It contains real retired Step 1 questions divided into three timed blocks of forty questions each, totaling one hundred twenty questions. It is delivered through the same NBME interface you will use on exam day at the Prometric testing center, which means the question layout, navigation buttons, highlighting tools, and block timing all mirror what you will face when you sit for the real thing.
