Subject: H3-1 exam prep 

I just wanted to thank you for your presentation, explanations and strategies offered in your NC H3-1 exam prep class. It's incredibly valuable information presented in a professional, no nonsense, efficient methodology that proved invaluable at test time and was THE difference in my confidence and ability to pass the exam the first time. 

Thanks again,    Ronald A Moore, II, K & B HVAC, LLC

 


I participated in the exam prep class on October 31 and November 1, 2020.  Just wanted to let you know that I did pass both business & law and H-3-1 on the first attempt yesterday.

What really helped the most was how you simply broke down what each codebook covered. The practice questions had the code reference and a description so I could determine if I was on the right track.

I appreciate the work and the detail that you have put into your prep class and study manual. I know how much work is involved and I applaud your work.

I was so excited leaving PSI yesterday all the work, all the study, the late nights, practice questions during lunch it all paid off.

Thank You for doing what you do I was 100% satisfied with your class and the way you made everyone feel so confident was priceless.

Mike -

I know you like feedback when someone from your class takes the PSI test. The good news I passed. I did everything you said to do.

Biggest help is to answer all the questions in your book in the back over and over again, that gets you real familiar using the correct book. The class definitely was the difference.
