Hello,

Here are a few points to consider in your situation:

• Check if you followed all instructions: Ensure you have bubbled the MCQ code correctly on the OMR sheet as well, as any mismatch can lead to invalidation.
• Barcode duplication: The barcode on the answer booklet and MCQ sheet being the same typically ensures proper linking, but any inconsistencies could cause issues.
• Stay calm: If you filled out the correct code in the answer booklet, it might still be processed.
• Verify with the exam authority: Reach out to the exam conducting body to confirm any concerns about code matching and validation.

For further clarification, you can also contact the relevant authorities.

Hope it helps !
