Hi,

According to the general criteria for MBA, the candidate must have done graduation in any stream along with atleast 50% marks scored in the bachelors for colleges. For NIT Silchar, the minimum marks are 55% and a relaxation of  5% is for those who belongs to Scheduled Caste (SC)/ Scheduled Tribe (ST)/ Person with Disabilities (PwD) category candidates.  Since, your score is lower than this, it will be quite difficult to get admission in NIT Silchar. However you can appear for entrance exams and try for other colleges.

You can refer to these links for more details: https://www.careers360.com/courses/mba-master-of-business-administration#MBA-Eligibility-Criteria and https://www.careers360.com/university/national-institute-of-technology-silchar

I hope this helped you.
