Course Description:

'' The Electrician Course is comprised of 14 comprehensive lessons. They are easy to follow, yet challenging and stimulating at the same time. Each lesson begins with a subject matter preview and objectives, an introductory note from your instructor and a vocabulary builder of new words and terms.

Next comes the reading assignment. Practice exercises help you check and review what you’ve learned. At the end of the lesson is an open-book exam, which you may take online.
