Degree

MBA & MS are equivalent. Mumbai University does not give MBA; they call it Masters in Management studies (MS). All other universities call it Masters in Business Administration. For your information, IIMS (all) offer only PGDM. But, they are most valued, respected and greatly in demand.

Please specify which PG programme you are looking to apply so that I can populate relevant details. Different courses have different criteria, and unless you name the course, I will not be able to help you out.

No, for doing MBA, you need a bachelor's degree. There is no provision of getting the direct admission without that.
Thank you.

Hi Aakash,
Yes, you can, you must apply for a study permit again before the older one expires. So while you are still doing your Diploma you have to contact colleges and universities in Toronto and try to fulfill the eligibility criteria.

I think if you choose sociology as your subject to appear in UGC NET it will be very beneficial. You can also take Development Planning/ Development Studies as a subject.

NCHMCT is the exam that you need to clear for getting in a college to pursue Masters in hotel management.

The basic eligibility for admission to MA in Mass Communication is a Bachelor's degree in any stream of minimum 3 years duration. It is not compulsory to have a Bachelor's degree in Journalism or Mass communication but it certainly gives an edge.
Regards.
