are cbse omr sheet of class 10 checked manually by the teacher? if not what happens if a student makes mistake in filling it??
OMR Sheets are not check manually by any teacher. OMR sheet for any examination is checked automatically by OMR machine which has a Scanner and the the sheet is sent inside the machine and it gets scanned.If you will fill any box incorrectly,it will read as it as.If you have not filled/coloured/marked any box correctly then it will not read that.
I hope this helps.
