To a layman, an OMR sheet is one that has lots of bubbles in the form of answer options. But that is not what distinguishes such a sheet from a normal paper. The OMR sheet has index points on its four corners due to which the OMR reader can record the marks made on the bubbles. If you are preparing for an exam that involves the use of an OMR sheet, you are likely to have several questions. One of the most important questions that you may have is how to erase on OMR sheet. Let us find out.
The answer to the question would depend on what type of tool is used to fill the bubbles; for instance, whether you are using a pencil or a pen. In case the examination center asks you to use a pencil, you can use an eraser if you have made a mistake. However, use a soft eraser and make sure there are no smudges. This is because a highly sensitive OMR reader may be able to catch even the light marks.
On the other hand, if you are using a pen for marking the bubbles, there is no way you can erase the marks if you think you are wrong. Using an eraser to rub off pen marks will only spoil the sheet. Also, you may tear it. Hence, it is best you avoid doing this. Moreover, using a whitener also does not work. So, it would be best to leave it.
One thing that you can do is that when you are in doubt about the answer, keep it for later or mark the option you think is right lightly by pencil. Once you are done with the entire paper, you can come back to the question and erase the mark with an eraser, and mark the right one with a pen.
As erasing on the OMR sheet is a difficult task, it would be best to be careful from the beginning. This not only includes the answer options but the candidate’s details too like roll no., question booklet no., etc.
