No,NMIMS Mumbai does not accept GRE for admission to their MBA program. The NMAT is mandatory to take. Most Indian B-Schools accept GRE or GMAT scores for their one-year MBA programs and in special cases, the admission team at NMIMS may consider an applicant who has taken the GRE if they like the applicant's profile. If you have a good GRE score, you could consider applying to ISB, which accepts GRE scores for its MBA program.
