e-A dmit Card
The e-Admit Card will be issued provisionally to the candidates through the NTA website: https://jeemain.nta.ac.in/, subject to the fulfillment of the eligibility conditions and receipt of the prescribed application fee by NTA.
The candidate has to download the Admit Card from the NTA website. The candidate will appear in the examination at the given Centre on the date and shift/timing as indicated in his/her e-Admit Card.
In case a candidate is unable to download his/her Admit Card from the website, he/she should approach the NTA Help Line Number: 011-40759000 between 10.00 A.M. to 05.00 P.M.
In case of any discrepancy in the particulars of the candidate or his/her photograph and signature shown in the e-Admit Card and Confirmation Page, the candidate may immediately approach the NTA Help Line from 10:00 A.M. to 05:00 P.M. In such a case, the candidate would appear in the examination with the already downloaded Admit Card. However, NTA will take necessary action to make corrections in the record later.
Candidates are advised to report at the Examination Center well on time i.e. 02 hours before the commencement of the examination.
Candidates should take their seats immediately after the opening of the Examination Hall. If the candidates do not report on time due to any reason i.e. traffic jam, train/bus delay, etc, they are likely to miss some of the important instructions to be announced in the Examination Rooms/Halls. The NTA shall not be responsible for any delay.
The candidate must show, on-demand, the Admit Card downloaded/printed from the NTA website for admission in the examination room/hall. The Test Centre Staff on duty is authorized to verify the identity of candidates and may take steps to verify and confirm the identity credentials. Candidates are requested to extend their full cooperation. Candidates who do not possess valid Admit Cards and authorized Photo IDs shall not be permitted to take the examination under any circumstances by the Centre Superintendent.
A seat indicating Roll Number will be allotted to each candidate. Candidates should find and sit in their allocated seats only. In case a candidate ventures to change his/her seat and doesnot sit on the seat allotted to him/her could face cancellation of candidature. No plea wouldbe entertained in this regard.
The candidate should ensure that the Question Paper available on the computer is as per his/her opted subject indicated in the Admit Card. In case, the subject of the Question Paperis other than his/her opted subject, the same may be brought to the notice of the Invigilator concerned.
The candidates may approach the Centre Superintendent/Invigilator in the room for any technical assistance, first aid emergency, or any other information during the course of the examination.
For any queries or issues regarding the Computer Based Test, the candidates may contact on Helpline Numbers available on the Joint Entrance Examination (Main) website.
In case a candidate, by furnishing false information, appears in more than one shift/date, his candidature will be cancelled and his result will not be declared.
For those who are unable to appear on the scheduled date of the test for any reason, a re-test shall not be held by the NTA under any circumstances.
Note: Candidates shall appear at their own cost at the Centre on the Date and Shift as indicated in their Admit Card issued by the NTA. Under no circumstances the choice of cities for the Centre and shift provided in the Admit Card shall be changed.
