Hi friends..My cousin sister who wrote ipcc accounts exam 2day made a mistake while writing the roll number in OMR sheet. She blackened the wrong circle. After realising the blunder, she pointed it out to the invigilator. The invigilator crossed the wrongly blackened circle & then blackened the correct circle. Will it be a problem since OMR data is read by computer? What do u people think? Have anyboby committed similar error in the past? Plz reply..
