The vast majority of business schools take only your highest GMAT score into account when evaluating your application. Why? First, it is in their best interest to inflate their mean and median GMAT scores to keep their rankings high. Second, business schools do not see the GMAT as a test of innate intelligence but rather as a measure of your preparation for business school. They want to know that at the time of your eventual matriculation, you will have the basic skills (quantitative, reasoning, writing, etc.) necessary for success in their programs. Whether you prove yourself on your first, second, or third attempt is irrelevant as long as you demonstrate your readiness somewhere along the way.
Also, keep in mind that business schools evaluate not only your academic qualifications (e.g., GMAT and GPA), but also your professional promise. They gauge this by your career choices and successes and by your demonstrated determination to succeed. If you present a GMAT score that is clearly below a school's standards, the admissions office will question your drive and consider you unrealistic. Taking the exam again shows determination and an appreciation for what it takes to achieve your goals, all desirable traits in a business school applicant.
How likely is it that your score will improve on a subsequent test? It is more likely than not. Many test-takers succumb to nerves on their first try, letting time slip away as they fumble through the exam. On a second attempt, the exam is no longer a mystery. Having learned from experience, many test-takers are better able to manage the time and to recognize the warning signs when they find themselves dealing with questions beyond their reach. Recent test-takers have gone from 620 to 720, 650 to 710, 580 to 670, 630 to 680, 520 to 690, and these are just a tiny sample of people whose scores improved significantly on a subsequent try. Of course, they continued to study and hone their skills, but an essential component of their eventual success was their prior experience with the exam.
If your first attempt at the exam falls short of your target score (i.e., a score that will make you competitive at the schools to which you plan to apply), you will need to take the exam again. But do not see this as a failure. Rather, it is a second opportunity to show the business schools that you are ready. In fact, we recommend that everyone plan to take the test twice, right from the start. The first try is a "practice run" to shake out your nerves and familiarize yourself with the timing and pressure of the real exam so that on your second attempt you can concentrate on the content and time management.责任编辑：虫虫
