I took Kaplan the last week in May. I took my boards on Monday June 23rd. I found out yesterday that I passed. I did QT1,2,3 prior to the start of class. I spaced the rest of my question trainers out and did #7 2 days prior to my appointment. I think one of the interesting things I found was this. Kaplan does not teach content----but as you go over the questions with the instructor you are reminded of content you might have forgotten and I even learned some brand new information that I had never heard previously. I, unfortunately, was unable to use the "decision tree" when I took my boards. The "DT" is not applicable to priority, delegation, SATA, and alternate format questions. Even saying that, though, I feel that I learned alot through Kaplan and it very well might have made the difference for me between passing and failing. Whether it is worth the money or not? Good question. If you don't pass you can use it for another 3 months or get your money back (if you follow all their instructions). I would be sure to purchase some other NCLEX review book. I like Saunders the best. Use the CD and answer those questions too. The estimated number of questions you are supposed to answer prior to boards (in order to be successful) is somewhere in the neighborhood of 5,000. I think that is probably about right for me. Blessings!
