Learn to Master this GMAT Data Sufficiency Strategy

Most of my GMAT students have a love/hate relationship with Data Sufficiency. At first, they hate it because it’s so foreign to them. It’s unlike any math problems they’ve ever had to do before. Eventually, after going through my GMAT Data Sufficiency video lessons, they learn to love ‘em. They learn to master the most common D.S. question types and apply the crucial strategies that make them so much easier.

One such strategy, for example, is to make up numbers for variables anytime you see them in the data sufficiency question stem or statements. This strategy makes otherwise esoteric questions much more concrete and attainable. Difficult problems become relatively easy. It enables you to out-think the GMAT and get more right answers.

Yet, students often make a crucial error when making up numbers of Data Sufficiency “Variable” questions: They choose numbers for those variables that simply aren’t allowed!

In fact, that’s my crucial GMAT tip for this free video lesson: When you’re making up numbers for variables on GMAT data sufficiency questions, those numbers must allow the statement(s) to remain true. In other words, your numbers can’t violate the veracity of the statements themselves.

This may seem like common sense, but the truth is that even some of my brightest students violate this simple understanding from time to time. Watch this video to learn exactly what I’m talking about and make sure you fully understand this simple tip, as it will enable you to get more right answers and dominate the GMAT!
