Negative Marks for Wrong Answers
If the answer given to any of the Multiple Choice Questions is wrong, ¼ of the marks assigned to that question will be deducted.
Interview: Candidates up to four times the number of seats available will be short-listed for interview on the basis of their performance in the entrance test subject to a minimum cut off. If candidates from outside India are unable to travel to New Delhi, they can seek permission for an interview through telephone/Skype/satellite. The final merit list will be drawn by adding together the marks of the Entrance Test and the Interview.
Separate merit lists will be made for (a) candidates from all SAARC countries other than India, and (b) candidates from India. Candidates will be offered admission from these two lists, according to merit, depending on the number of seats available.
