Score difference with Rapid replies versus Omission (GMAC)

Hello, deeppan. I downloaded and read through the article. I am curious, what specifically did you find of interest in an academic article that was written in 2009 about an earlier version of the test? To me, the language is unnecessarily stuffy, and fifteen pages could be summarized in a graph or two. The takeaway for me was that rapid guessing, defined as that which is done in 10 seconds or under for Verbal questions or 7 seconds or under for Quant, often leads to lower scores the more often such a strategy is employed. That seems like an obvious point. Moreover, the analysis on whether it is more advantageous to rapidly guess or omit an item has limited applicability. Both lead to lower scores, the kind that I doubt most readers on this sort of forum would be targeting.

Do not get me wrong, I love to pore over data, and GMAT™ data interests me greatly. I would simply like to know which points of the article captured your attention and why. Why recommend this article to others?

Thank you for sharing.
