"gonna be honest i put off studying till like three weeks before my date and panicked. ended up doing the practice questions on njecexam.com every night after work, mostly focused on overcurrent protection since i always mix those rules up. passed with room to spare, still surprised."

"mistake review feature was the thing that actually helped, kept showing me the same raceway questions i kept blowing until it finally stuck. exam felt long but not too different from the practice sets tbh."
