GIBS Business School is a good college, and getting admission is quite achievable for both BBA and PGDM programs. For BBA, you need to have completed 10+2 with decent marks, and for PGDM, you need a bachelor's degree and a good score in exams like CAT, MAT, or CMAT.
GIBS also considers interviews, group discussions, and overall profile, not just scores. As a student, I feel it's a college that gives great learning, exposure, and opportunities, and I'm happy with my choice.
