ℹ️

Scoring method: Microsoft reports results on a scaled score from 1 to 1,000, and 700 or greater is required to pass; the scaled score is not a percentage of questions answered correctly, and items may carry different weights. Microsoft does not publish the split of scored and unscored items. Results are normally shown when the exam ends, with a score report showing performance by skill area; beta exam results are released later.. The exam may include unscored pilot questions - treat every question seriously.
