With our exam prep program you will be able to go into an examination with confidence knowing exactly what types of questions to expect, what reference materials are used, and how the questions are written and phrased. Familiarity with these code and text book questions is a must to pass your state examination.

Timed computerized exams can be difficult without preparation. Therefore, practicing sample tests, questions, answers, and code references repeatedly is critical for you to become an effective test taker.

Our program has a Study and Review mode that allows you become familiar with the material prior to taking your sample tests. The Test mode allows you to gauge your understanding of the variety of topics that will be required to pass the state exam. Our questions are scrambled each time you test to simulate your actual state test experience. Your goal with our program is to get your test scores at home above 95% within the time limit of your exam. Begin to Prep At Home with an immediate digital download.

Important Notes:

  • Refer to your candidate information bulletin provided by the State or the testing agency to get a complete list of which reference books can be taken into your exam.
  • Candidates are responsible for bringing their own references to the examination center. Reference materials may be highlighted, underlined and/or indexed prior to the examination session”. (Permanent tabs and highlighting is permitted. No notes !!!)

The trend has been over the last 5-10 years for the state examinations to be developed out of the code books that the State and the inspectors have adopted, rather than base questions on practical or “hands-on” experience. This is the main reason that our software program is so vital to your exam preparation. The majority of our customers are experts when it comes to installation and service for their specific trade, but are not proficient with timed computer examinations that are based on text and code book topics.

Since we know that you are going to have to answer questions from specific code book sections, we focus our effort to develop exam prep materials for those sections. This allows you to focus your time and effort on these topics, and not misuse your time simply reading through the code book.

Here are some sample questions from our exam prep program:
