I fully attribute my verbal improvement to e-GMAT. After I subscribed to e-GMAT trial i realized the approach they were using was very useful in my case and i subscribed the verbal online course .The audio visual files followed by short Quiz for assessing the improvement was one key approach that helped me throughout this course . Moreover the difficulty level and content structure of Quiz in each section was as per Module covered (like if one has covered modifier and parallelism one will not encounter any idiom question ) which helps in determining the improvement rather than getting demoralized when failed to solve one due to a concept not covered. Another tools of E-Gmat that helped me are Quiz review Section and Scholaranium.
On the one hand Quiz review section consist of detail analysis to the quiz and an ask an expert option for asking my doubts and shows doubts from other students (which covered most of my doubts ) and Scholaranium on the other hand gives my progress in hand at anytime which helped me a lot in deciding which section i should focus more as i progressed through the course , which i think is the most critical .
At last i want to thanks to all e-GMAT team members ( Rajat, Payal ,Anubhav, Krishna & Shraddha ) for their support and feedback .
