Maximize Your GMAT Readiness
As you know if you’ve taken several full-length practice tests, your score will vary, and it won’t always do so in a logical fashion. You might have gotten up on the wrong side of the bed one morning and saw your score drop 30 points; another day you might see a run of questions that you’d just practiced and get a much better result.
There’s no research to prove this (nor do I think there will be: it would be just about impossible to control for all the variables involved) but I suspect that, the day you take the test, there’s a range of about 50 points that your score could fall into.
Several factors determine whether you end up at the high end of the low end of that range; some of those are within your control, others are not.
The single thing you can do to best guarantee that you will score on the low end of your range is to see a question you’re not prepared for, let yourself flail at it for five minutes, and then stress out about how you’ve ruined your time management. That may sound like something you would never do, but it’s much more common than you think.
