The GMAT is a necessary hurdle on your way to business school, but sometimes it’s hard to see why. What do these multiple choice questions really have to do with a masters in business administration? If this question plagues you, take a look at this recent post from the GMAC. It explains exactly how two types of questions”data sufficiency and critical reasoning”measure abilities required by business schools.

Data Sufficiency. This question type, which requires you to determine what’s necessary to solve the problem, is ultimately a test of your ability to weed through minutiae for the important details. And sorting through information is an essential skill set, given the data-rich nature of the modern business environment, says Booth School of Business professor Pradeep Chintagunta. To successfully manage in this environment requires translating the data into usable information, he says, adding, The skills tested by the Data Sufficiency part of the test are consequently critical to managerial decision making.

Critical Reasoning. These questions probe your ability to evaluate the relative strengths of arguments. If you can handle a critical reasoning question, you’re prepared for collaborative b-school projects requiring you to judge others’ ideas. And those projects, in turn, are designed to get you ready for the real world. MBA programs can provide students with decision-making processes, says Valter Lazarri, MBA director of the SDA Bocconi School of Management, Milan, but they need a raw ability to connect facts, to detect patterns, to discriminate true causation from spurious correlations.

Of course, it is easier to sort through information when you understand its substance”hence our content-based curriculum.  And don’t fret if you’re struggling in these areas. With diligent practice, you can develop your natural abilities.
