AMBOSS → Step 2 CK FAQs
How accurate is AMBOSS Self-Assessment for Step 2 CK?+
The calculator applies an internal AMBOSS source adjustment, but a reproducible validation study is not published. Combine it with a recent CCSSA or Free 120 and use the full range.
Why does AMBOSS over-predict?+
We do not publish evidence for a universal AMBOSS offset. Differences may reflect question mix, timing, or the population taking the assessment, so this site labels its adjustment as an internal assumption.
Should I take AMBOSS Self-Assessment if I have NBMEs?+
Lower priority. Use AMBOSS as a content review tool; rely on NBMEs and Free 120 for prediction.
