Testimonial from email received on 10/17/16 for class taught on September 10, 2016 and the State exam on September 12, 2016.
I just received my mechanical exam test results and I passed all the exams I tested in. A huge thank you is in order, just passing the tests the first time was worth more than the cost of your class. I couldn't have done it without your very professional and comprehensive class. Your exam study guide was worth its weight in gold, with up to date practice tests and ton of reference material needed to pass the exam. It even included current Senate bills not yet passed and changes to the law not always easily found elsewhere but still essential to passing the exam. What I took most from your class was not memorizing the huge amount of information, but more importantly the teaching of the method of how to look up and reference information quickly. The testing was approximately 6 hours, It was a race for the clock with little time and knowing how and where to reference material quickly was more valuable than the information itself
