Accidentally bubbling in two test booklet codes (47 and 48) may affect the validity of your answer sheet. It's crucial to understand that the OMR (Optical Mark Recognition) system, which scans and reads the answer sheet, relies on correctly filled bubbles to accurately identify your responses.

Filling multiple bubbles for the same question or code is generally considered an error and may lead to the question being marked as incorrect or even invalidating that particular section of the answer sheet.
