    Dear Friends, i had an exam today where i had to mark the answers on OMR answer sheets.
    But unfortunately in some answers i marked a bit out of the circle, will it lead to rejection

    It's actually optical 'mark' reader.
    No, generally it is a single photodiode that measures each circle, it doesn't look outside the circle and doesn't take a picture. As long as you blocked enough of the circle to reduce the light, it will mark it.
