I just passed the Series 6. The Solomon Audio/CD set was essential for me as I spend 1.5 hours per day in my car, so that became my study time! Thank you for providing an audio/cd version! I have just ordered the Series 65 set as well.
I passed the 24 with the help of the audio, book and test questions. I previously took this test and failed walking away with the thought nothing I studied looked familiar. I also didn't really understand how certain areas functioned... but found the information provided with Solomon worked best for me. The flow charts and extra resources section were extremely helpful in breaking down sections of this "Dry" test. The audio was great to review and the book format was easy to read and concise. I felt almost every question I knew what they were asking and I was able to eliminate one or two questions. Don't waste your money with other sites. Solomon will allow you to pass on the first time. Good luck!
