Thanks Muneeb for the response and I have enrolled for E-GMAT's sentence correction. Hope, this brings in the desired result. As of now,I plan to stick to E-GMAT and in case, this doesn't improve my score signifiantly and then I would consider Aristotle SC Grail.

In my humble opinion Aristotle SC grail is better than MGMAT SC guide, because its more crisp and to the point, on the other hand MGMAT SC is the ultimate guide (if you appreciate content depth). Additionally, all SC prep should focus on the OG, some like to build more background before they attempt the OG, so it really depends how much information you want to know before you attempt the OG questions. Aristotle SC offers a shorter path so does GMATPREPNOW. Whichever path you take, you should plan on spending some extra time reviewing those OG questions. Mastering the OG questions will put on the road to GMAT success.
