The GMAT score you'll need for the Indian School of Business (ISB) can vary depending on your profile, the competitiveness of the applicant pool in a given year, and other factors such as your academic and professional background. However, ISB typically looks for candidates with a strong overall application package, which includes not only a competitive GMAT score but also relevant work experience, leadership potential, academic achievements, and a compelling personal story.
While there's no fixed "cut-off" score, it's generally recommended to aim for a GMAT score above 700 to be competitive for ISB. Scores in the range of 710-750 are quite common among successful applicants. However, it's essential to remember that the GMAT is just one aspect of your application, so make sure to focus on strengthening all components of your profile.
Additionally, ISB also accepts GRE scores, so if you're more comfortable with that exam, you can consider taking the GRE instead. Ultimately, aim to achieve a score that reflects your abilities and potential as a business leader and complements the other aspects of your application.
