Really Helpful for Sentence Correction

20 Days before the exam, I still had very low confidence on my accuracy in Sentence Correction.

Even though I had read the Manhattan SC book and learnt some concepts, I was not able to apply these learnings while practicing Official Guide Questions primarily because of its lack of practice questions similar to OG.
I also felt that concepts taught in the Manhattan SC book were a bit easier than those tested in Official Guide, though the explanations were very clear and I felt I learnt a lot from the book.

Confident that my SC prep was not upto the mark, I started searching for online resources.

Trying to save some money, I collected all the SC PDF's available on gmatclub forum. I eventually (2-3 days later) realized that even though the free resources had good material, I found myself reading a new doc every few hours and was unable to focus on one. At the end of 2-3 days, I realized I had not learnt anything concrete.

This was an unnecessary wastage of time and I quickly decided to buy a good course to help me focus on only 1 source of learning. Going through the reviews, it was clear that e-GMAT verbal is amongst the best, and definitely the best for non-natives. Without thinking twice, I subscribed for the Sentence Correction course (which was available individually at that time).

I decided to devote one complete week (of the 18 days remaining) to e-GMAT sentence correction. I found the course extremely helpful. All the concepts were very clearly explained and all the edge cases were covered too. Their 3 step approach helps you in breaking down a long sentence in smaller easy to understand part. This was an extremely helpful technique.

The practice quizzes and questions were really good and of the level of Official Questions.

One word of caution, when I was following the course I was practicing questions topic by topic. Hence they are a bit easy to solve because you know what type of error is going to be in the question. Even thought the course always advises to use the 3 step approach, I felt it is not possible to do this when you are trying to quickly solve these questions ( or maybe I had little time to internalize this approach).

Hence I will advise to keep some time to solve official question, after getting done with the E-gmat course. With the concepts taught, it is possible to get at least 90% accuracy depending on the time and efforts one puts.

Overall, it proved extremely helpful to me, even in the short time span of 3 weeks and helped me get 730 (V:40).
