Good Job.....are you game?

I work with many electricians who say they are good. But they can't pass quizzes.
Try this one it's free and use Master Electrician Reference to find the answers.
It's free, free , free while others will charge you for without covering practical questions.
All of the questions are free ...not for a few...then they charge you for the rest like others do.
Trade practice, NEC and General purpose questions are’s a wireman quiz.

The questions are suspect, I do not recommend this app for those who seriously want to have a practical Electrical understanding you're better off paying a couple dollars in purchasing the NEC Challenge app. The NEC app, questions on the book you'll be asked questions about. Imagine that
