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!

I had a great experience. The best thing about it was that I could schedule the exam whenever it was convenient for me. My exam date wasn’t until January, but I was able to get started right away. The explanations were easy to understand and even when I didn’t know the answer to a question, I could still figure it out.
