NDD practice questions - frequently asked questions

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

The NDD exam spans 16 domains: Normal development (4-6%); Genetic and developmental disorders (8-10%); Cognitive disorders (8-10%); Learning disabilities (7-9%); Communication disorders (6-8%); Autism spectrum disorder (8-10%); Attention-deficit and disruptive behavior disorders (7-9%); Motor disabilities (8-10%); Developmental psychiatric disorders (4-6%); Neuro-ophthalmologic and neuro-otologic disorders (4-6%); Neurodevelopmental disorders associated with major medical conditions (5-7%); Brain and spinal trauma (4-6%); Epilepsy and episodic disorders (1-3%); Neuroimmunologic and paraneoplastic CNS disorders (1-3%); Disorders due to toxins, drugs, and physical agents (4-6%); Questions not associated with a specific neurologic disorder (5-7%). Every practice question on this site is tagged to one of these domains.
