Hey Mike:
Just letting you know I got the official word today that I passed my H2 exam (1st try).  I didn’t have time to do any additional study, so the only prep I had was the class on sat and sun, then the exam Monday morning.  Thanks for the help.  Great class.

I extend my appreciation to The Technical Training Institute. I have passed the Business Law as well as H2 and H3 . Your method of teaching proved very much worth the time and money I spent.  I really appreciated the fact that I had a question during my studies in the last few hours . I emailed and got a simple prompt explanation … I passed …
I would highly recommend you guys and will do my continuing education with you.

Good Morning Mike, Just wanted to drop a line and say thanks. After taking your Heating Exam Prep course August 14 &15 and studying with your methodology, techniques and material I was able to pass the H-2  license on August 31st. Your information was challenging and your advice was right on. I will be taking the H-3 Class 1 Exam within the next few months.
Thanks for your help,

Mark Reavis

Your advice worked! I was nervous about taking all three of my exams within a two week period but it was the best thing that i could do. Your material helped me out a lot. I was able to pass my H-3, H-2 and H-1. Thanks for all of the help. I will absolutely recommend your class to anybody that is trying to get their license. Almost  forgot to tell you thanks on the SP-PH Electrical License too, your class helped me pass that exam.
