The GRE is essential to get into graduate school. So! Students willing to study in graduate school in countries like the USA, Canada, and many more or want to secure a fellowship (merit-based) for graduate school must sit for this exam. All graduate schools in foreign countries demand a GRE score for admission in both masters and Ph.D. programs.
More than 1,200 business schools that offer top MBA programs accept GRE scores. Also, GRE scores are required for masters and doctoral programs. In short, a GRE score will be needed for at least one of the programs you are applying for. Without GRE scores, you will not be able to take admission in any master’s or Ph.D. programs. If you want merit-based funding, then you are required to sit for the GRE.
GRE scores will be valid for five years, so you can appear for the GRE if you have a plan to apply to graduate school within five years for a master’s or Ph.D..
