Best verbal course out there for a non-native speaker

I used the various courses out there to try and improve my verbal score but nothing would stick. I would always get stuck between 2 answer choices in SC and would only pick the correct one 50% of the time. After taking e-GMAT's verbal online course, I understood how the sentence would change meaning with the way the sentence is structured. This skyrocketed my accuracy are helped improve my overall verbal score. Their SC module is the best I've seen and if you're struggling with SC there is nothing better than this out in the market. Additionally, the CR module was great to help me identify how t pre think the answer but not be 100% sold on my answer.
