Awesome Course for Non-Native

I had already taken a good known verbal course and even after studying verbal part, I was not able to answer verbal questions. Then I found online webinar from E-Gmat and was very impressed with their methodology of Pre-Thinking. With Pre-thinking method and dividing SC questions into parts was very helpful. I started understanding SC questions much better after going some of the verbal online tutorials. Also I found related GMAT OG questions at the end of every tutorial; these really help to sync with official guide. For RC, I was not very sure if I should just skim the passage or read whole passage as I feel I am a slow reader. I learnt 7 step method from E-GMAT after which I realized that though first question takes more time as you are reading the whole passage and taking notes, but then you can answer rest of related passage much quicker.
