Xavier Institute of Management and Research

Xavier University will be a better option than other because of its best course curriculum, faculty, placements, and so on.

ILS registrations will be confirmed after CAP Round 3, depending on the number of seats available. So, keep an eye out for that and call the college around then to register for the same.

You can consider JBIMS, KJ Somaiya, Sydenham and Welingkar for MMS.

Yes, you can and there is no procedure for it though. You can either apply for any competitive entrance exams for this or next year effectively or join any MBA college or B-schools which still have admissions left. Although percentage or CGPA at least till 65% of full-time degree are sometimes taken into consideration while applying for admission.
