Best verbal course for non-native english speakers

I started my GMAT journey 4 months ago , and I was on the lookout for a comprehensive verbal course that could give me a good foundation on the basics.
After using the e-GMAT verbal live prep over the course of a few months, I can say with full confidence that this made a difference to my preparation. Like most other non-native speakers, I evaluate words and sentences based on how it sounds in my mind. This required me to unlearn certain basics, and that is not an easy task. It takes multiple visits to the concepts in order to have it etched in my mind and come naturally to me under a pressure situation like the GMAT.

The well-focused Sentence Correction does exactly that. It goes over the basics over and over until you get it correctly each time. The live classes are very helpful, and by breaking down each part of the sentence, the confidence to solve a SC problem skyrockets.

Overall, I used the e-gmat for SC(indispensible), for CR(good), Scholaranium(indispensible) In addition the OG solutions for SC and CR are very clear in their reasoning, and saved me a ton of time that I would have spent otherwise hunting for answers from so many other sources and comments online.
