e-GMAT verbal Review: Path to improve verbal score

I am a non-native and I scored 38 in Verbal and 50 in Quant. I am targeting to reach 750+ on GMAT. I was struggling to find the right course for a very long time and after going through several reviews I opted for e-gmat's Verbal course. Course provide structured way to learn basics and then move to advance level. Course has significant number of video to explain concepts and constitute 400+ average level problems and 600 advance level problems in scholaranium.
After completing basic video and tests, i improved my average score in mocks by 3 points. Solving scholaranium questions and other tests, i managed to take my score in range of 41-45.
