Missing your signature on the CUET OMR sheet can be a cause for concern, but it's not necessarily disqualifying.

The National Testing Agency (NTA) has a verification process for OMR sheets. This process involves scanning the sheets and checking for inconsistencies or missing information. If your OMR sheet is flagged for a missing signature during verification, it might delay your result or require further action from your end.

In some cases, the NTA might overlook a missing signature if all other details are filled correctly and the invigilator's signature is present. They might prioritize ensuring the validity of your answers over a missing signature.

You might receive a discrepancy notice from NTA informing you about the missing signature. The notice might ask you to provide a written explanation or submit a copy of your admit card with your signature for verification.
