Hello,
Yes, it is. For admission to M.Sc, you have to first clear the IIT JAM exam. JAM exam is conducted for admission in IITs, NITs, or IISc to pursue M.Sc (four semesters).
JAM Exam will be conducted on February 10, 2019. So, you still have time left. Start you JAM preparation now.

Invariably all state governments have put a restriction on admission of students in engineering colleges within the state. Domicile is the prime requirement. Hence, you need to take admission in a college in the state in which you have domiciled. So you must work hard.

The admission date is over. You are supposed to wait till next year, if you are so interested in it.

You must look up for the list of colleges of Delhi and Mumbai that are of your interest, and check if they have got any entrance exam for further level of studies that you wish to pursue.
