Can I join an MBA college without taking any entrance exam?

Hello! If you're aiming to study full-time MBA in any reputed college, then you need to appear for the particular entrance exam(s) whose score is accepted by such a college, clear its cutoff (s), and perform well in the interview rounds (if shortlisted for them). Admission is given purely on merit
