When it comes to admission requirements both the GRE and GMAT test scores are considered valid by the admission committees of all business schools and universities across the globe. However, if you’re certain about enrolling in an MBA programme in India or abroad, then it is better to opt for a GMAT test since GRE may have slightly lesser scope than the GMAT test. If you’re not sure whether you’re going to be studying a masters in business or tech, then it is advisable to opt for the GRE since it offers better flexibility than the GMAT. Hence, it all depends on your higher education goals.
