Some of the reasons of NEET OMR rejection is provided below:

• If the name bubbles are not filled in correctly
• If you have bubbled your roll number incorrectly
• If more than one center is filled, as this misleads the team who corrects the answer sheets, which then leads to cancellation of the answer sheet
• If you have put your signature outside the designated box
• Extra markings around on your answer sheet may also lead to cancellation of the OMR sheet
• If you have not filled in the bubble correctly, as in if its half filled and half not filled
• If you have marked outside the bubble
• If you have filled outside the bubble
