FACTS
The GMAT is becoming more competitive every year.
The median GMAT scores and cut-off GMAT scores for almost every school have steadily increased in the last few years.
The GMAT is becoming more difficult every year.
The GMAT scoring is less accurate at high score levels. Because more students are doing well in the math section, the test takers have started incorporating more difficult questions and more advanced topics to relieve this score clustering.

The GMAT is becoming more international every year.
In the last ten years, the number non-U.S. citizens taking the GMAT has risen an incredible 47%. According to Frederic McHale, senior VP of assessment and research at the General Management Admission Council, which administers the GMAT, Chinese, Japanese, and Korean nationals score an average of 70 points higher than their North American counterparts.
The GMAT is becoming more crucial every year.
Because of the dramatic improvement in the ability of test-takers, schools are faced with a slew of high GMAT scores; the schools have started using higher GMAT scores in their own ‘process of elimination’.
The GMAT is becoming more accessible every year.
With Pearson VUE’s broader reach, computerization of the test, and with the rising fortunes of the Asian middle-class, more and more international students will take the GMAT. Most of this expanded pool of test takers has superior quantitative skills.

Now consider these facts
Over the past few years, the number of GMAT questions involving statistics, permutations & combinations, probability, and geometry has increased substantially.
Unlike the vast majority of GMAT concepts, most test takers do not cover these subjects in high school or college.
The test makers rely on these topics to create the most challenging problems, heightening the difficulty of the test.
Despite the growing number of these questions, the presence of these topics in test preparation guides and courses remains conspicuously limited.
Test preparation companies are lagging behind the recent trends, and do a disservice to the test takers by not exposing them to these more difficult concepts and questions.
"The GMAT is not an intelligence test," says Rod Garcia, director of MBA admissions at MIT's Sloan School of Management. The average score attained by applicants accepted at Sloan is 703. The concepts tested in the GMAT can be learnt, practiced, and mastered using the right tools and prep material.
Your GMAT score is probably the most important factor in determining whether you will be admitted to a top business school. |
