AD practice questions - frequently asked questions

Plain answers about how AD 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 AD exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The AD exam spans 4 domains: Basic Science (25% of the exam); Laboratory Evaluation of Autonomic Function (25% of the exam); Clinical Autonomic Disorders (25% of the exam); Clinical Management (25% 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: Basic Science 25%; Laboratory Evaluation of Autonomic Function 25%; Clinical Autonomic Disorders 25%; Clinical Management 25%.

The AD exam has 200 questions and is completed in 4 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
