ADEX practice questions - frequently asked questions

Plain answers about how ADEX Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real ADEX exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The ADEX exam spans 9 domains: Restorative (24% of the exam); Prosthodontics (19% of the exam); Oral Pathology, Pain Management, and Temporomandibular Dysfunction (13% of the exam); Periodontics (10% of the exam); Oral Surgery (9% of the exam); Endodontics (8% of the exam); Orthodontics (6% of the exam); Medical Emergencies (6% of the exam); Prescriptions (5% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Restorative 24%; Prosthodontics 19%; Oral Pathology, Pain Management, and Temporomandibular Dysfunction 13%; Periodontics 10%; Oral Surgery 9%; Endodontics 8%; Orthodontics 6%; Medical Emergencies 6%; Prescriptions 5%.

The ADEX exam has 148 questions and is completed in 5 hours 10 minutes. Our timed practice mirrors that length and pacing, so exam day feels familiar.
