If I have made a mistake in my OMR form, can I erase or use a whitener to clean up and write the correct information?
Dear aspirant,
Make sure to not make a mistake in an OMR sheet as you have mark the answer it will become kind of permanent in that place and if you try to initiate it might lead to some problem with readability for the software whitch check the sheet.
in some cases you are allowed to Mark with pencil and you can erase it but I suggest you must first solve the question on the rough part given the question paper and then only mark the answer.
As for the whitener you are not allowed to use whitener in any sheet.
Hope this helps. Thank you.
