Is 680 a good GMAT score?

In my years of experience, I've found that a GMAT score of 680 can be considered quite good. It indicates a strong grasp of the tested subjects and showcases solid critical thinking and problem-solving abilities. 

However, it's important to understand that the significance of a GMAT score can vary depending on the program you're applying to and the competitiveness of the applicant pool. While a score of 680 might be competitive for some programs, others may have higher average scores. 

Therefore, it's essential to research the average GMAT scores of the programs you're interested in to get a clearer picture. Additionally, remember that admissions decisions are not solely based on GMAT scores; factors such as work experience, academic background, and extracurricular activities also play a significant role.
