One thing which i noted in the article is about the credibility of the authors, both of them from Top careers from you have one striking similarity - Both of them haven't cleared CAT themselves !!! JB and IMI are the two institutes which u don't get if u are in the top 2-3 percentile in CAT, so i don't see how their comments can help the lakhs of people who are taking CAT this year.
This is just for the benefit of large number of readers of this article
