Best resource for verbal prep

I am Non native English speaker. I have tried various sources for my verbal prep and tried to remember a number of rules without understanding the concepts, just scoring around V19.

I came across e-gmat in gmat club and attended free webinar on sc. After the class I got some hope that I can improve, so I went all in with e-gmat live prep course.

Concept files are excellent with simple expels to understand the concepts. I learned more than half of the verbal concepts for the first time on e-gmat platform. Live class great to learn the application of the concepts learned. I am more confident now than I was at the beginning of my prep. I highly recommend this course, especially, for those who need to build up their concepts from scratch.

Thanks E-gmat for your support in building up my arsenal to face gmat exam.
