A must course for all

I am an native English speaker, however during my pre, I realised there are some mistakes I was making in the Verbal section in GMAT, which I was unable to understand. I tried many courses online, but none of them really helped me, and my score in verbal was consistently low.
Then, on my friend's suggestion and GMAT Club reviews, I came across e-GMAT,which changed my perspective of VERBAL completely. The way in which it is divided in topics, with test after every topic. And an explanation after each question, made it even more interesting and self-explanatory. And most importantly, it suggested me ways to reach the answer, in the shortest amount of time.
It is a must for all who wish to succeed in the Verbal section of GMAT
