NO practice questions - frequently asked questions

Plain answers about how NO 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 NO exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The NO exam spans 4 domains: Adult Primary Nervous System Tumors (35% of the exam); Pediatric Primary Nervous System Tumors (25% of the exam); Metastatic Cancer to the Nervous System (15% of the exam); Systemic Cancer-Related Neurologic Disorders (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: Adult Primary Nervous System Tumors 35%; Pediatric Primary Nervous System Tumors 25%; Systemic Cancer-Related Neurologic Disorders 25%; Metastatic Cancer to the Nervous System 15%.

The NO exam has 200 questions and is completed in 4 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
