How good is Fr. Agnel Business School, Vashi for MBA?

It is not recommended if you're looking for some serious good placements and opportunities with good designated salaries, the college mentioned is very new and is not much renowned either.

It's a pretty average B-school, so not recommended. There are much better colleges(Sydenham, KJ Somaiya, Welingkar, NL Dalmia, etc.) which you should consider. Still, if you're interested, then keep it only as a backup option. I hope it helps.
