65 discipline items split 62% Clinical, 28% Scientific, 10% Community — the NBDHE's Component A weighting — plus two patient-case testlets for the case-based half: an adult periodontal patient and a child.
Straight multiple-choice alongside the exam's own EXCEPT, paired true-false, and cause-and-effect items — so it reads like the test, not a flashcard deck.
Every item carries a full rationale — why the right answer is right, and where the tempting wrong answers go astray. You read them in your review after scoring.
Your results name your weakest NBDHE sub-area — Pharmacology, Radiographs, Periodontics, and the rest — and route you to the matching practice.
