One of the most popular features of AMBOSS self-assessments is the 3-digit score. This score is intended to give you an idea of where you currently stand in your USMLE® preparation. To get a 3-digit score, you must complete all four blocks (that’s 160 questions) of the AMBOSS Step 2 CK Self-Assessment by 11:59 PM PDT on May 15, 2022.

If you complete the self-assessment, you’ll receive a score report on May 19 with your score as well an analysis of your performance and personalized study recommendations. 

How the 3-digit score is calculated

The score you’ll receive after completing the AMBOSS Step 2 CK Self-Assessment is calculated using the performance of self-assessment-takers that are within weeks of their actual USMLE Step 2 CK exam date as a reference to calibrate the scores. In addition, we use a statistical method called “item response theory” which estimates the proficiency of each individual exam-taker and the specific questions they answered for score calculation. That means getting a very challenging question right will have a greater positive impact on your final score than getting an easier question right.

The scores of the reference cohort are checked against data from actual USMLE Step 2 CK exam-takers. The minimum, maximum, and mean scores are all assessed in the reference cohort as well as in the entire cohort of AMBOSS Step 2 CK Self-Assessment participants to ensure their accuracy.

The passing score

As you may have heard by now, the passing score for the USMLE Step 2 CK exam will increase from 209 to 214 on July 1, 2022. As this change won’t come into effect until then, the passing score for the 2022 AMBOSS Step 2 CK Self-Assessment remains 209. You can read the official announcement from the USMLE here

Once the self-assessment is over, we’ll be working hard to get you your 3-digit score as fast as possible. You can expect to receive a score report on May 19, 2022. 

Best of luck!
