The GMAT is a standardized test used by graduate business schools to assess applicants. It measures verbal, quantitative, and writing skills over four sections. The test adapts questions based on the test taker's performance, starting with medium difficulty questions. Over 1,600 schools accept GMAT scores. Proper preparation is important, including taking practice tests to learn strategies and build speed and familiarity with question types. The quantitative section covers math fundamentals while the verbal section evaluates reading comprehension and critical reasoning abilities. Test takers should practice managing time on the integrated reasoning section which contains unique question styles.
