 What our students have to say about their Exam Prep Course

Date: February 6, 2014
Subject: I passed

I am writing to let you know that I passed my contractor H3 class 1 license exams.  I was the one who sat up front and was pretty sick the whole two days we were in class.  I wanted to let you know how I did it so that you can use it as an example for others.  I tried to listen and apply what you told us. 


During the exam:  Business law, I looked up everything, as much as I could and marked the ones I could not find quickly. just like you taught us. 


I thought I did well, but was not completely sure that I passed.  I know that I would not have passed without your course and I am very confident that you were the best instructor for the course.  Your knowledge of the material amazed me.  If I need to take another course I will be sure to go to your classes and I will absolutely recommend your courses to anyone.


Thank you,

Just wanted to thank you for all your help and encouragement.  I got my letter today…I couldn’t believe it as I thought the test was definitely harder this time than others and felt even worse Friday night, but I know that all your prep helped in getting me through it ok. Thanks again and I’ll see you in CE classes.

Just wanted to let you know that I took your class on April 10th and 11th and took my H-3 Class 1 Exam on Monday April 12th. Well I just wanted to let you know that I passed both exams business and technical the first time, had it not been for your class I'm sure it would have taken more than one time.

So thanks for all the help and advice see you in cont. ed.

Thanks Again

Subject:   H31 Exam results For Jeff R

I took your prep course on Oct. 26-27.  I took the H31 exam on Nov 1, that was a tough 5 hour exam. But I managed to pass the first time, only because I took your class and used your methods. You had stressed  the time restraint for the business and law, which I managed to finish.  The technical part was another story.   When I left the exam I did not think I passed, but I was wrong - I did PASS, Ya buddy.   Thank you for your help.
