The four-part exam measures your Analytical Writing, Verbal, Quantitative, and Integrated Reasoning skills—higher-order reasoning skills that management faculty worldwide have identified as important for incoming students to have. Your GMAT scores provide a standardized, statistically reliable measure of how you are likely to perform academically in the core curriculum of a graduate management program.
The GMAT exam is delivered entirely in English and solely on a computer. It is not a test of business knowledge, subject matter mastery, English vocabulary, or advanced computational skills.
Launched in 1954 by a group of nine business schools to provide a uniform measure of the academic skills needed to succeed in their programs, the GMAT exam is now used by more than 5,200 graduate management programs at approximately 1,900 institutions worldwide. Hundreds of prestigious B-schools in India that include ISB and IIM’s are now accepting GMAT scores. Thus, if you want to join a prestigious Business school, you need to take GMAT most of the times.
The GMAT is presented on a computer in the form of a Computer Adaptive Test. This means that the computer changes or ‘adapts’ to your performance and present questions and generate scores basing on your performance.
Well, it is one of the measures, not the only measure for your selection. While it is surely an important component of your selection process, other factors, such as your academic performance, your work experience, your admission essays, your Statement of Purpose and many other factors are considered for your admission. However, your test score may be important for the very consideration of other factors. Thus, you cannot ignore this score.
