Feedback from licensed and aspiring electricians who used these tests
"The code application questions for master level are tough and they should be. A few of the questions I felt were worded a bit ambiguously but that might be realistic for how the actual exam reads. Good resource for advanced prep."

"Decent site but some of the questions feel a little outdated, not sure if they are updated for the 2023 NEC or an older edition. Still usefull for getting familiar with the code format. Would be better with more state-specific questions."
"I work in construction management and needed my journeyman card to move up. Used this site every evening for two months. The tests get harder as you go which I really liked ??? by the time I hit test 20 I felt ready for anything."
