HI Dipak,
To enrol for MCA, you have to first give an entrance exam of the same to get admission in any college.
Search for colleges which are participating to give admissions through the entrance test.
The basic requirement is that you're either a graduate from BCA, BSc IT,BSc CS, BSc maths and much more.
Hope it helps.

it is of a duration of 2 years. to be exact 1 and a half years because at the end placement and all starts and hence classes do not occur.

The post-graduation course of M.Sc is of 2 years span, as per the guidelines of UGC. Rest, I will advise you to contact the university, which give you the most appropriate and authentic answer to your queries.

The eligibility criteria for studying for doing M.Sc, is having done B.Sc from a recognized university. Next, what you require is to have made up to the minimum percentage the college you chose requires in your graduation in order to be eligible to take admission in post-graduation.
