One of the great learnings I had during the e-GMAT Verbal Online course was the innovative problem-solving approach, which is based on meaning and pre-thinking. Verbal Online is carefully designed from student's perspective, specifically teaching a step-by-step process to solve various items being tested.
For Sentence Correction, Verbal Online helped me to adopt a methodical process to understand the meaning thereby helping me to improve my overall accuracy. My accuracy for Sentence Correction shot up to 75-80% after incorporating e-GMAT's approach of solving SC questions.
Similarly, the RC and CR courses focus on pre-thinking, which is yet another important and effective method to achieve higher accuracy. I used Scholarium to focus on my weak areas and thoughtfully watched the videos to excel in my weak sections.
For a non-native speaker, Verbal Online is worth every penny and I would highly recommend it.
