I wanted to share my experience with the Gmat preparaton, I hope this can serve to the community.
In my first attempt in the gmat I got 650 (Q50V27), my mother tongue is Spanish and I started learning English a little late. In my first attempt I studied the books of Manhattan,
the Official Guide, and private classes; All this built my theoretical knowledge very well. My first simulations were in the 650 range, so a 650 on my first try was logical. After the test I felt a little worried because I knew I could do better, but I did not know how. I did well in SC, but I was slow to solve CR and RC.
In my second attempt I got 690 (Q50V32). After my first attempt I went to get help on the forums, and I found Rich's comments. Which at first seemed acidic to me, but now I have to accept that he was right. My preparation for the second attempt was with some more private lessons. I read a lot of "The Economist", I solved more official exercises. And I enrolled in his Empowergmat Verbal course. I have to admit that Empowergmat's approach gave me a better perspective to solve the exercises. I did some more simulations, which continued in the 650 range, but I felt more confident this time. Then I stopped performing simulations; and focused on speed and understanding the logic of the question, rather than understanding word for word exercises. I finally got 690 on my second attempt. This time, after the exam, I did not feel worried given I knew I could have had a better result and that it was basically with more practice. However in my schedule I had already decided to give the Gmat on that date.
I just have to thank the EmpowerGmat team, they certainly gave me confidence and a good approach to take the exam. This time the Gmat episode was finished and I have to continue with the following parts of the application.
