Best GMAT Verbal course for non natives

i started gmat prep in feb 2017 and in april i took first mock, scoring 590 and 22 in verbal. It was devastating for me because I never thought that i would score so low. expectation were much higher. this score was after two months of preparation from manhatten verbal guide and jamboree quant material. in may i bought egmat SC online course and from this point of time things got changed because the problem was not prep material nor it was concepts because i was very clear with concepts. problem was something else which i was not able to figure out
the whole problem was in my reading strategy what i came to know only after joining egmat.
GMAT is all about reading and interpreting

few observations about egmat

1. course is so lively that even a live class teacher cant match impact of egmat modules
2. best part is that every module is arranged in chronological order and word by word interpretation really help in correting the reading habit.
3. when one is through all modules he do not need to remember concepts, concepts just come in to habit

my experience with GMAT

I devoted 90% of time to verbal even then failed to manage timing in verbal section because of nervousness.
I marked last 8-9 questions in just two minutes without even reading. I dont know how these questions impacted my score, but for sure if i had managed time better score would have been better.
avoiding nervousness is impossible but try to manage as much as you can.

last thing reading newyork times during prep can help in SC and RC.
