Kaplan won't let you down if you are willing to put forth some effort.

Though I was hesitant to enroll in such a pricey course, I have zero regrets. I had studied for months using the ETS books that I had purchased on Amazon and my score was way below the minimum requirement to even apply for the program I am interested in. With Kaplan, I was able to study in a more structured manner. My coach helped me to create a study schedule for each week so that I would be properly prepared by test day. After each practice test, he would give me areas to focus on and it was so helpful to have his guidance. The classes are nice because you can get feedback as you are working through different practice problems. The GRE is definitely not an easy test, but Kaplan will help your score improve if you are willing to do the work. This class will give you valuable strategies and familiarity with the test material, but ultimately it is up to you to put in the hours of studying to make it happen.
