Delia Adkins (verified owner) –
I was really worried about this exam. I had three weeks to prepare for it and barely did any studying because I didn’t know what to study. My wife got me this guide just two days before the exam and recommended that I listen to it while commuting to work and while doing chores around the house. It was amazing! I studied only 4 hours before the exam and passed. Thank you so much!!

Preparing for the exam using the exam testimonial was a smart move. I wanted to ensure that I was fully prepared and so I used these materials as a basis for my studies. The materials are clear, concise and easy to follow. As a result of my hard work, I passed the written portion of my test the first time!

I took the exam and passed without difficulty. The questions were very similar to the questions provided by the study guide and practice exams on the website. I would like to thank you again for the study guide! Without it I am sure I would have failed.
