10 Questions based on Jade Learning’s Demo Exam

 

Not too long ago we were talking about putting together a website that would have an online simulated exam that would give electricians electrical exam questions similar to the actual electrical exam.  On top of providing electrical questions, we wanted there to be a score report at the end of each simulated exam that would break down the score by the electrical exam subject areas.  We figured if electricians had a practice test that would also grade them the same way the real exam does, they would have a better chance of passing the electrical exam by knowing what subject areas they should focus on.

Well, after some research we found out that not only was our idea a great one but that someone else had already come up with an online simulated exam prep for electricians who were taking their electrical exam!  Here are 10 questions based on Jade Learning’s Free Demo simulated electrical exam.  Not only should you quiz yourself now but you should follow this link to register to take their free demo so you can see what it actually looks like.  You will find the answers to these questions on Jade Learning. If you get the wrong answer, Jade Learning provides you with the correct question as well as reference on the electrical code book or step by step calculation explanations.

Since the PSI electrical exam is computer based, it is very important to start getting used to taking the electrical exam on a computer.  You don’t want to be caught off guard the day of the electrical exam if you are computer shy.
