Day of the JEE Advanced 2021 Examination

Candidates must carry a printed copy of the downloaded admit card and their original photo identity card for the examination. Only candidates having a valid admit card will be allowed to write the examination. The candidates will be given the original admit cards upon identity verification during the examination.

The candidate’s identity will be verified by invigilators as well as IIT representatives. If the identity of the candidate is in doubt, the candidate may not be allowed to appear in the examination. However, the authorities at their discretion may provisionally permit the candidate to appear in the examination after completing certain formalities. No extra time will be allowed for completing the examination in lieu of the time taken for completing these formalities.

Impersonation in the examination is a serious offence and will lead to disqualification of the candidate from JEE ( Advanced ) 2021.

Only pens, pencils, downloaded admit card and an original photo identity card are allowed to be taken inside the examination hall. Candidates will not be allowed to carry any electronic devices ( e.g. mobile phones, smart phones, calculators, iPAD, tabs, digital watches etc. ), abacus, slide rule, log books, study material of any type, geometry box, written or white ( blank ) paper / piece of paper, wallets, etc. to the examination hall. Candidates are advised not to wear items containing metals such as rings, bracelet, earrings, pendants or cloths with big buttons.

Candidates must report to the examination centres well in advance. Candidates arriving at the examination centre after commencement of the examination in each paper ( 9:00 IST for Paper 1 and 14:00 IST for Paper 2 ) will not be allowed to take the test.

Candidates are required to be present in the examination hall for the entire duration of each paper. They cannot leave the examination hall before 12:00 IST for Paper 1 and before 17:00 IST for Paper 2.

Both Paper 1 and Paper 2 are compulsory. Therefore, the responses of only those candidates who have appeared in both Paper 1 and Paper 2 will be evaluated / graded.

In case, the examination Board of Class XII ( or equivalent ) declared the results for the academic year 2019-20 before June 2020 but the result of a particular candidate was withheld, then the candidate will not be eligible to appear in JEE ( Advanced ) 2021.

Earlier admission at IITs

A candidate should not have been admitted in an IIT irrespective of whether or not he / she continued in the program (or) accepted an IIT seat by reporting at a reporting centre in the past. Candidates whose admission at IITs was cancelled after joining any IIT are also not eligible to appear in JEE ( Advanced ) 2021.

Candidates who have been admitted to a preparatory course in any of the IITs for the first time in 2020 can appear in JEE ( Advanced ) 2021.

JEE Advanced 2021 Reservation of Seats

Indian nationals belonging to certain categories are admitted under the seats reserved for them in accordance with the rules of the Government of India. The categories and the extent of reservation are as follows :

  • Other Backward Classes belonging to the Non-Creamy Layer ( OBC-NCL ) – 27% of seats in every course. The backward class should be in the current updated central list of OBCs

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.

  • Scheduled Caste ( SC ) – 15% of seats in every course. 
  • Scheduled Tribe ( ST ) – 7.5% 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 ( websites : and ).

  •  Persons with Disability (PwD) – 3% seats in each of OPEN, OBC-NCL, SC and ST category seats.

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.

Candidates belonging to the OBC-NCL, SC, ST and PwD categories will be declared as qualified on the basis of a relaxed criterion.

Unfilled seats in the OBC – NCL category will be de-reserved to OPEN category seats. whereas, 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.

The category of a candidate as entered in the database, which will be made available by the JEE Apex Board [ which conducts JEE ( Main ) 2021 examination ], will be final and requests for change of category will not be entertained.

Defence Service ( DS ) Candidates

Defence Service ( DS ) category candidates are children of defence / paramilitary personnel killed or permanently disabled in action during war or peacetime operations. Two seats are available for preferential allotment in each Institute for DS candidates. To avail of this preferential allotment, a DS category candidate must be in the Common RankList of JEE ( Advanced ) 2021.
