How to Pass the Licensing Exam

Know the format cold

Most electrical licensing exams are multiple choice and open book, meaning you can use your code book. Many are split into a code-knowledge portion and a calculations or theory portion, and often include business and law for master and contractor levels.

Find out exactly which edition of the code your exam uses and whether it is open book. Walking in blind to the format is the easiest avoidable way to fail.

Tab your code book

On an open-book exam, speed is everything, and speed comes from knowing where things live. Tab and highlight your book before test day: the common tables, the ampacity and conduit-fill tables, the calculation articles, and the definitions.

• Tab the tables you will flip to constantly.
• Practice the index until finding a topic is reflex.
• Do not over-tab; a book with a hundred tabs is as slow as none.

Drill the calculations

The calculation questions are where people lose the most points, but they are also the most learnable because they repeat. Practice load calcs, box fill, conduit fill, voltage drop, and motor and conductor sizing until the steps are automatic.

Work timed practice exams, not just isolated problems. The clock is a real part of the test, and getting comfortable under time pressure is half the battle.

Strategy on test day

Answer the easy questions first and flag the hard ones to return to; do not burn ten minutes on one problem while five quick points sit unanswered. Read every question fully, because the exam loves the word except and the trap of two almost-right answers.

Sleep, eat, bring your calculator and tabbed book, and arrive early. Preparation beats panic every time. Do the reps beforehand and the exam becomes just another day of doing what you already know how to do.
