Find your weak spots before the NBDHE finds them.

Seventy-five board-style questions built to the NBDHE's own blueprint — 65 discipline items across the three domains, plus two patient-case testlets. In about 45 minutes you'll see exactly where studying moves the needle, down to the sub-area, and leave with a plan.

What makes it worth 45 minutes
01

Built to the blueprint

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.

02

Real board formats

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.

03

You learn as you go

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.

04

It pinpoints the fix

Your results name your weakest NBDHE sub-area — Pharmacology, Radiographs, Periodontics, and the rest — and route you to the matching practice.
