e-GMAT SC course

I took my GMAT exam in September 2013 & was not happy with my score. I’m fairly good at Quant, but to score well in verbal, I needed a good Sentence Correction (SC) score. My friends from my GMAT Preparatory Coaching Institute recommended the SC course of e-gmat.
I am a non-native speaker of English & certain nuances of the language have always escaped me for some reason under the pressure of time constraints. I read the Manhattan GMAT Sentence Correction book, and found it very useful, but it could not match the Audio-Visual (AV) approach of e-gmat.
In my view, e-gmat is an excellent course, mainly due to the AV approach of teaching, which is akin to a classroom environment. Sections in any AV module or lesson could be stopped and played again numerous times at any moment for fortifying the conceptual understanding of the topic. Also, examples when played out in an AV format tend to get embedded with the concept better, as compared with classroom study or self-study. Moreover, all topics are summarised in brief PDF’s for quick reviews before exam day.
I recommend anyone having problems in understanding SC concepts to first do e-gmat. For more advanced topics, the Manhattan GMAT sentence correction book can be referred, as one would have already acquired a solid foundation to tackle the advanced topics.​
