DNC practice questions - frequently asked questions

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

The DNC exam spans 3 domains: General Dermatology (55% of the exam); Surgical Dermatology (30% of the exam); Phototherapy (15% 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: General Dermatology 55%; Surgical Dermatology 30%; Phototherapy 15%.

The DNC exam has 175 questions and is completed in 4 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
