Here are the eligibility criteria for PGDM / MBA at GIBS Bangalore, in a simple and generic way:
You need a Bachelor's degree (3- or 4-year) with at least 50% marks from a university recognised by AICTE / UGC / AIU.
Final year graduation students can also apply (provisionally).
You must have a valid entrance exam score: CAT, XAT, CMAT, MAT, ATMA, GMAT, or the applicable state-CET.
Work experience or additional qualifications gives you extra advantages in selection (optional, but helps).
ALL THE BEST!
