The Best Verbal course i came across

I started my GMAT with classroom courses in Delhi, and then took to manhatten, but my score did not improve much. I was stuck at 630-640.I was not sure what was i was missing , then a friend of mine who had given his GMAT recently and scored 740 in just 2 months suggested me E-GMAT Course.
I took the online course and not the live prep. To my surprise it suggested to understand the concepts first unlike my classroom course with an institute in Delhi which emphasized on shortcuts.

It took me 2 months to complete verbal and the mock scores have improved a lot. my last score was 710.
The course explains the concept and application very well. I can easily identify the errors from the question sentence itself now, well i need to memorize all the concepts still. most of the time i forget the concept. I would really recommend it to everyone who is struggling to improve the verbal score.

I am yet to give the GMAT in December and i hope my actual score is consistent with my mock test scores.
