Hey,
Masters of Business Applications(MCA) is a three year postgraduate programme that deals in various aspects of Computer applications.
It is entirely your call as to where you want to study.
You just need to make sure that the ranking of the College is good as per NIRF.The faculty and ambience matters the most along with the placement cell of thar College.
See,the Business Schools have different aura and the placement cell is generally better as most of the companies prefer going there. But,yes everything depends upon you. Ultimately,it's your hardwork and passion that will help you get through all the ordeals.
Hope this helps.
Good luck.
