Important points in JEE Mains-2018:

  • There shall be No weightage for the 12th class marks in calculating the ranks in the JEE (Main)-2018 examination
  • No JEE Mains without Aadhaar: The candidates will have to enter their AADHAAR number, name, date of birth & gender which will be validated with the UIDAI's data. In case, these particulars do not match, the candidates will not be able to fill the application form for JEE (Main)-2018. Therefore, the candidates are advised to ensure that their AADHAAR card has correct details of their name, date of birth & gender as per school records. If there is some mismatch in these details, the candidates should immediately get it corrected in AADHAAR data or school records, as the case may be.
  • For the candidates to qualify for the admission in the IITs/NITs/IIITs and such other CFTIs whose admissions are based on the JEE (Advanced)/JEE (Main) ranks, they should have secured at least 75% marks in the 12th class examination, or be in the top 20 percentile in the 12th class examination conducted by the respective Boards.
