27% of seats in every course. The backward class should be in the current updated central list of OBCs (http://www.ncbc.nic.in ).

Candidates belonging to the creamy layer of OBC are NOT entitled for reservation. Such candidates are treated as belonging to the general (GEN) i.e., unreserved category, and they will be eligible only for the OPEN seats – the seats for which everyone is eligible .
15% of seats in every course.

The benefit of reservation will be given only to those castes and tribes that are mentioned in the respective central list of corresponding states published by the Government of India http://socialjustice.nic.in/UserView/index?mid=76750 and http://tribal.nic.in/Content/StatewiseListofScheduledTribesProfiles.aspx.

Benefit would be given to those who have at least 40% impairment irrespective of the type of disability i.e., locomotor, visual or SEVERE dyslexic.

Leprosy-cured candidates who are otherwise fit to pursue the courses are also included in this sub-category.

Unfilled seats reserved under OBC-NCL category will be de-reserved to OPEN category seats. However, seats remaining vacant under the SC and ST categories shall NOT be de-reserved to any category. The reservation for PwD candidates is horizontal and hence, unfilled seats will be de-reserved to the respective categories i.e., unfilled SC-PwD seats will be converted to the SC category seats and so on.

Candidates belonging to the OBC-NCL, SC, ST and PwD categories will be declared as qualified on the basis of relaxed criteria. See Rank Lists .

Candidates who are NOT citizens of India (by birth or naturalized), do not belong to OCI/PIO category, and whose parents are not citizens of India and do not come under OCI/PIO category at the time of registering for JEE (Advanced) 2017 are treated as foreign nationals. Seats allotted to foreign nationals are supernumerary with a cap of 10% of total number of seats in every course.
