"This past Saturday I took the CPE exam, after having followed your CPE Exam Success Plus course. Obviously I don't have the test results yet, but I felt very comfortable taking the test. I liked the hands-on practice tests, which prepare you for the type of questioning the exam uses. Also each week gives some theoretical background and rules to refresh your memory, I kept those!
Above all that I think your client-oriented attitude grabbed my attention. I once wrote a comment to your website and received a response within 1 day. A day prior to my exam you sent me an email wishing me luck. I think that besides the quality of your exercises the level of customer service makes your company stand out. I will most certainly recommend your on-line courses!
With kind regards,"
