In most multiple-choice question (MCQ) examinations, candidates are instructed to completely darken the OMR bubbles. This ensures that the marks are read accurately during scanning. Some exams, however, allow alternative marking styles such as tick marks or single-line markings.
Because the majority of institutions use the Addmen Optical Mark Reading (OMR) Software for evaluating OMR answer sheets, they usually provide strict guidelines requiring students to fill the bubbles fully and neatly.
Technically, the Addmen OMR Reader Software is highly adaptable and flexible. It allows administrators to adjust reading sensitivity based on the marking style permitted for the exam. This means the software can interpret:
Fully filled bubbles
Partially filled bubbles
Tick marks
Thin lines
Overfilled or spilled marks
This adaptability ensures that even if a candidate does not fill the bubble perfectly, the Addmen OMR Answer Sheet Checker can still read the responses with high accuracy.
Even if the bubble is:
Not completely filled
Filled lightly
Overfilled or crossed slightly
Marked outside the bubble
Slightly smudged or abraded
…the Addmen OMR software can interpret the response correctly thanks to its advanced recognition algorithms.
The latest advancements in Addmen OMR technology help the system maintain accuracy even in the presence of:
Smudges or scratches
Abrasions or minor paper defects
Faint or uneven marks
Slight misalignment
This makes the software highly reliable for large-scale examinations and ensures fairness for all candidates.
