Journeyman Electrician Pre Test

Although this quiz is called a Journeyman Electrician Pre Test quiz, it is designed to help a prospective student determine if they need to enroll in the Journeyman course before entering the Master Electrician course.

Here is a ten question quiz of material best understood by an applicant before enrolling  for the Master Electrician License Exam Prep Course as instructed by David U. Larson.

Allow 24 minutes total at one sitting.

Be adult about the time limit.

Now this quiz is my own attempt to warn prospective students that skipping the Journeyman level material and diving into the Master level material might not be a good idea.

Well, let the results of this quiz guide you in your decision.

If you miss none, one, or two questions, that's great. Skip the Journeyman course and enroll in the Master course.

If you miss three or more questions, completing the Journeyman course before enrolling in the Master Electrician License Exam Prep is a good investment in your future success.

Good Luck. David U. Larson

The quiz.

Remember, 24 minutes. You will need a 2011 NEC and a calculator.
