The GMAT (Graduate Management Admission Test) scores are used by business schools as part of the admissions process for MBA and other graduate management programs. The GMAT score range is typically between 200 and 800, and the score is based on performance in the Verbal and Quantitative sections of the test. The Analytical Writing Assessment (AWA) section is scored separately on a scale of 0 to 6, and the Integrated Reasoning (IR) section is scored on a scale of 1 to 8.

A score of 620 falls below the average GMAT scores for many top-tier MBA programs. The average GMAT score for admitted students at competitive business schools is often in the range of 700 or higher. However, what is considered a "good" GMAT score can depend on the specific requirements of the schools you are applying to and the competitiveness of their admissions process.

Here are some general guidelines to consider:

1. Research School Requirements:

   • Different business schools have different expectations for GMAT scores. Research the average GMAT scores of admitted students at the schools you are interested in to understand their specific requirements.

2. Consider the School's Average:

   • If your score is close to or above the average GMAT score of admitted students at a particular school, it may be considered competitive for that institution.

3. Holistic Admissions Process:

   • Business schools often consider various factors in addition to GMAT scores, such as work experience, academic achievements, letters of recommendation, and personal statements. A strong overall application can compensate for a slightly lower GMAT score.

4. Retaking the GMAT:

   • If you are not satisfied with your GMAT score and believe you can achieve a higher score with additional preparation, you may consider retaking the test. Some applicants take the GMAT more than once to improve their scores.

5. Consider the Entire Application:

   • Admissions decisions are typically based on a holistic assessment of an applicant's profile. A strong application package that demonstrates leadership, relevant experience, and a compelling personal story can sometimes offset a slightly lower GMAT score.

Ultimately, what is considered a good GMAT score depends on your personal goals, the competitiveness of the programs you are applying to, and the other strengths in your application. It's advisable to reach out to the admissions offices of the schools you are interested in to gain insights into their specific expectations and to assess the overall competitiveness of your application.
