Recommended for self paced study for GMAT

My main focus for taking e-gmat was for improving my verbal score. My verbal score was 27 first time around and 34 after taking the course.
The verbal course is well structured. Modules for each topic covers exhaustive concepts tested in exam and clearly explained. I just went through all videos and practice questions and quizzes. Questions in scholarium are descent GMAT level questions.
Meaning based approach for sentence correction questions really helped me improve accuracy for SC questions. With systematic method taught for critical reasoning , I could easily answer difficult level questions.
Sigma mocks also gives a GMAT like experience and gives in depth and ESR analysis
