Mode

Exam fidelity: Microsoft does not identify the specific item types that will appear on an individual exam before delivery. This lane counts multiple-choice and multiple-response items as exam-style practice. Ordering and matching are supplemental learning exercises and do not count toward exam-style accuracy. Difficulty labels are calibrated to AB-900 Fundamentals, not a Microsoft-published question rating.
