At AddMen Group we frequently see one of the most critical mistakes candidates make: forgetting to fill the roll-number block on the OMR sheet. Whether you’ve left the bubble matrix empty or failed to write your roll number at all, this can lead to serious issues in automatic evaluations. Our OMR reading software relies heavily on the roll-number data to identify and match answer sheets.
The roll number establishes your unique identity behind the answer sheet and links your responses to your candidature.
Most OMR-reading systems first read the bubble format roll number. If that’s missing or unreadable, the software often triggers a manual validation alert.
If neither the bubble format nor the printed/written roll number are present or legible, your sheet can be skipped or excluded from automatic evaluation.
This is still acceptable in many cases. The software reads the bubble input; the written number is only a backup. Your sheet will usually be processed.
This is risky. Without any roll‐number identifier, the sheet may not be evaluated. The system may reject or skip the sheet altogether.
When the bubble section is blank or unreadable, our software triggers a prompt for manual administrator review.
If handwritten roll number is provided, an evaluator may manually fill the bubble format based on the handwritten number, and proceed.
If there is no roll-number information at all, the only option is to skip the sheet — meaning your responses may not be counted.
Before you start the exam, fill the roll-number section first (both bubble format and handwritten if required).
Ensure you darken the bubbles completely and correctly — partial marks may lead to mis-reading.
Read all the instructions on the OMR sheet carefully — many sheet rejections stem from ignoring instructions.
If you realise you made a mistake, immediately inform the invigilator; it may allow a manual correction before data processing.
Maintain calm — while forgetting to fill the roll number is serious, many institutions allow manual verification if the written roll number is present.
Q: If I forgot to write the roll number in words but filled the bubbles, will my sheet be rejected?
A: No — in most cases the bubble roll number is the primary input. The written number is a backup. The risk is lower in this scenario.
Q: What if the OMR software can’t read the roll number bubbles?
A: The software will trigger a manual verification prompt. If written roll number is available, the evaluator may fill the bubbles manually and process the sheet. If not, the sheet may be skipped.
