Many a true word is said in jest.—I don’t know, but I heard it from my mother.

When I was a little boy, I didn’t want to be a fireman when I grew up.  I wanted to be a riverboat gambler.  Unfortunately, I didn’t because of a bad upbringing—utility stocks were too risky for my father. . .I do play poker and blackjack some though.  And I don’t try to fill inside straights.  On the other hand, I don’t play baccarat because I don’t understand the rules well enough.  The same principles apply to the GMAT.  The first part of this series—-Heart of Darkness—A Holistic Guide to GMAT Scoring —- highlights why test takers don’t score as well as they should because they don’t understand the rules of the game and thus often try to fill inside straights.  And, like a Greek tragedy, that post ends by lamenting how even test takers who know how to play baccarat are corrupted by the siren song of the ticking clock.  Yes, the clock.

Folks fail to understand that all their good work will be undone if they do not finish the sections in good order.  Leaving the last five blank will lower your score by as much as sixty points.  Roughly speaking, doing so in both sections will magically turn a 660 into a 550.  And you must not only finish, but also finish in good order.  If you blind guess the last five in each section, with average karma, your score will still drop sixty points.   Run the assessment reports on your practice exams—if your score is lower than the average difficulty of the questions that you missed, you have timing problems, even if you are finishing the sections.

How can you avoid this penalty?  Well, the easiest way is to have an angel on your shoulder and always guess right.  However, if you can’t count on that angel full time, you have to control the clock. In the first half of a section, the CAT computer is roughly approximating your ability level.  Thus, what is unforgiveable there is missing questions that you know how to do.  But test takers misunderstand—that is NOT the same as getting them ALL right.  If I take a GMAT, I’ll get ten of the first fifteen quants correct.  Maybe eleven.  Or maybe nine.  It doesn’t matter.  For me, after about the fourth one, they are all 800 level questions and, as part one discussed, you only need to be about 50% accurate at the score level that you want.  Trying to get them all right is a trap.  First off, as I implied a second ago, even if you are scoring 790, the computer will give you problems that you don’t know how to do.  So it’s hopeless on the face of it.  Equally importantly, attempting to do so uses up too much time.  The Catch-22 here is that you must answer those that you know correctly without disproportionally using the time.  Or you’ll turn your 660 into a 550.  What is the solution to this dialectic?  The envelope, please. . .
