Many deserving students fail the highly challenging All India Sainik Schools Entrance Examination (AISSEE) because they fill out their OMR sheets incorrectly due to a lack of knowledge. Optical Mark Recognition (OMR) technology is used to analyse AISSEE, so even minor errors in answers cause rejection.
This blog explains how to fill the Sainik School OMR sheet for Class 6 and 9 correctly, how you can avoid common mistakes, and tips on how you can avoid these mistakes.
Understanding the Importance of the OMR Sheet
The OMR sheet is scanned digitally. The system only recognises appropriately shaded circles and full details. Any mismatch, overwriting, or inaccurate marking may result in a loss of marks or possibly disqualification.
The OMR filling rules are the same for Class 6 and Class 9; therefore, every candidate must follow them properly.
1. Download and Practice Sample OMR Sheets
- Go to the (National Testing Agency) website, download sample OMR sheets.
- Under the exam time limit, practice for a week before the exam.
- This helps improve accuracy, speed, and confidence.
2. Carry the Right Writing Tool

- Fill the OMR with black or blue ballpoint pens only.
- Don’t fill the OMR with pencil or any other coloured pens.
- Carry at least two working ballpoint pens to the exam centre.
