It's all about the qbank! And Kaplan has the best.
The best part about Kaplan is undeniably the Qbank. The key to the MBE is not watching videos or reviewing outlines, it is all practice, practice, practice. The MBE can only ask you so many types of questions with so many variations, if you take all the practice questions, you will recognize the same ones on the test and know the answers from experience. I used the tutor mode with 20-50 question intervals to see and understand what I was doing wrong in real time.
