NERC TO practice questions - frequently asked questions

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

The NERC TO exam spans 6 domains: Resource and Demand Balancing (13% of the exam); Transmission (29% of the exam); Emergency Preparedness (10% of the exam); Emergency Response (16% of the exam); Contingency Analysis and Reliability (20% of the exam); Communications and Data (12% 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: Transmission 29%; Contingency Analysis and Reliability 20%; Emergency Response 16%; Resource and Demand Balancing 13%; Communications and Data 12%; Emergency Preparedness 10%.
