Which exam to opt for admission in ISB hyderabad, GMAT or GRE?

Of the two entrance exams, GMAT and GRE, the former is a better option. ISB Hyderabad has recently started accepting GRE scores. This doesn’t mean that taking the GRE is a bad idea. Many business schools apart from ISB are now accepting GRE scores. The best part is that ISB won’t be converting your GRE scores to GMAT for comparison during the MBA admissions.

• GRE is suitable for students who are considering other PG options apart from MBA like MS or MA. 
• For someone who is sure of their career in an MBA, the GMAT is a better choice because GRE is much more dynamic. GMAT shows your commitment to MBA and thereby increases your chances of admission in comparison to GRE which shows that you are open to various options.
• ISB Hyderabad prefers GMAT over GRE also because the former is a more quantitatively challenging exam than the latter. 
• Certain firms may ask for your GMAT score before shortlisting you for your interview. These include the biggest firms in the corporate world like McKinsey

So from these points, we can safely conclude that GMAT is a better option for MBA students provided that you are sure of your course.
