Last August 2020 I passed the Series 28 on the first try using your materials. I just wanted to drop in and let you know I passed the Series 27 exam today!! I am so happy today as I took the test in Jan of this year and missed it by 3 points. I switched up my focus and really zoned in the most heavily weighted chapters. This is by far the hardest exam I have taken. Thank you Solomon for your excellent study materials. I'll be back when I pass the next one ;)

I passed my 27 and I can't thank you enough for the preparation materials, most importantly the Final Exams. I studied for weeks for this test and buckled down the last two weeks of 6 hour study days. It's a great feeling and I couldn't have done it without you!!!

Questions from the exam simulator were pretty similar to the actual series 52 exam, and I felt prepared with the study guide. I will be purchasing the series 53 study materials from Solomon in the near future.

I just passed the series 24! It is, by far, the hardest test that I have ever taken. I had failed it 4 times using other study materials. I have never felt more defeated! Solomon Exam Prep is the best! I took over 154 practice tests...without seeing the same question twice. I was able to finally grasp the material and passed! My only regret is that I did not use the Solomon Exam Prep on my first attempt!

I've used the Solomon exam prep materials for both my SIE and Series 6 exams and passed both on the first try! The audio materials are a lifesaver and a great resource to utilize, especially while driving. Also, your team is fantastic! I reached out through the "Ask the Professor" option while studying for the SIE and the response and additional help was exactly what I needed. I highly recommend Solomon! Thanks again!
