How many answers should be shaded per question on the OMR sheet?

When filling out an OMR (Optical Mark Recognition) sheet, it is essential to shade only one answer per question. This practice ensures clarity and precision in the scoring process, as the OMR scanner is designed to read the sheet based on distinct markings. If multiple answers are shaded for a single question, the scanner may not be able to properly interpret the response, which could lead to incorrect scoring or a result being marked as invalid.

The objective of OMR sheets is to facilitate a quick and accurate assessment of responses, and adhering to the guideline of marking only one answer helps maintain the integrity of the results.
