These in depth classes teach you how to use both the Code Books and the Manuals necessary to pass your examinations.

It is not the intent of this class to teach you the exact test content, but to teach you how to answer the type of questions that may appear on the examinations.

The success of our class relies upon the unique combination of the following:

• Computer Based Training
• Student and Instructor Interactive Seminar
• Detailed explanations and problem solving of various math (i.e. Load Calculation, Duct Design)
• Additional Home study questions

Don't try to cram all your study into 1 weekend. Most people need additional time at home to study and become proficient with the material in order to pass the examination.
