Good platform to judge your Verbal power for GMAT

I'm an Architect and have been preparing for GMAT. I completed the study materials and so reserved the appointment for taking GMAT. After this I started taking short quizes in e-GMAT scholaranium keeping a month timeline to practice. Pretty soon I realised that I'm very slow in reading and comprehending which affects both CR and RC, but somehow moderate speed in SC. There is this score report with different data such as accuracy, difficulty level and the time taken by most of other students who correctly answered that specific question. This helped to me to evaluate and understand where was I lacking and standing compared with other students. This is a very good and efficient tool to judge and streamline your preparation.
