Multiple-choice questions are generally asked in these day's examinations, for which OMR answer sheets are used. For all the available four to five options, students need to mark/fill the correct bubble without confusion, so to avoid the need for erasing incorrectly marked answers. While the latest OMR readers can be customized to read tick marks and half-filled bubbles, it is still imperative for all students to fill the bubbles completely if the instructions on the OMR answer sheet specifically mention it. Older OMR technologies are incapable of accepting tick marks or half-filled bubbles though, but Addmen OMR software is quite flexible when it comes to reading the bubbles.
The Addmen OMR software comes with the facility to customize the reading sensitivity as per the standards set by the concerned educational institution.
It can be fed reading parameters such that it would also read tick marks or half-filled bubbles.
Overfilling mistakes or stray ink spilled on the paper should not ideally be a problem if the examination body uses OMR software to evaluate the sheets.
Addmen OMR software’s reading process is not hampered by dirt or scratches in the OMR sheets.
Most examinations specifically instruct the candidates to fill the bubbles completely. But here are a few points to be noted:
For filling these bubbles, use an HB pencil or a ball point pen, as specified in the sheet filling instructions
Use of whiteners on the OMR answer sheets for correction is strictly discouraged, but exam bodies using the Addmen OMR software for evaluations won’t face any issues.
If erasers are used, they must be of fine quality and should be able to erase even the light marks completely. Older OMR scanners will even read the light marks. Also, ensure that you do not damage the paper due to excessive erasing.
Addmen OMR scanner software is able to read tick marks and half-filled bubbles. However students should not take this as an advantage as they cannot judge which sort of OMR scanner the institution is using. So be careful while following the instructions of the board before filling the OMR sheet.
