I took the exam for the first time last week and passed! I was so excited. I was pretty nervous going into the exam, but it ended up being much easier than I expected. The test prep materials on your site were very helpful.

The key to success is to identify the type of learner you are. If you know that you learn from reading, and watching videos on the same day, then this course is for you. I have been a professional for many years and needed a course that was interactive, and if that is the best way for you to learn, then this course will be very beneficial for you.

The exam material was great and the practice exams were a lot like the real test. I signed up for the course a few weeks before my exam date. I used the study guide a bit to refresh my memory on certain areas of the course. Right before my exam, I took about 2-3 practice exams and then took my exam. The practice exams really helped me out because I felt more comfortable with how the actual test was set up.

I was very nervous and didn’t know what to expect. So I asked my friend who had taken the exam before, he told me to take the free sample test questions and use them as practice. I did and I passed! Thank you!
