hello student,

OMR sheet is only evaluated on the basis of darkening of the bubbles.

it should be done by blue or black ball point only.

here are some guidelines issued by CBSE regarding OMR sheet responses-

Students are required to use only black or blue ball point pens to fill out their OMR sheets, and under no circumstances will students be allowed to use pencils.

CBSE has instructed students to darken the circle of the correct answer (a, b, c or d) for any question. However, the board has also made provision for the student to revise their choice of option.

In case a student has already darkened the circle option, but they later think that the response they chose was incorrect and wish to choose another option as the correct one, they can do so by writing the answer they deem to be final and correct in the box. This is the reason that CBSE has provided a box. However, it must be noted here that the box needs to be filled out by the student in any case, as leaving the box empty would lead to the question being deemed as unattempted regardless of whether the circle has been darkened or not. On the contrary, if the box has been filled but no circle has been darkened, the question will be taken as attempted and the student will be marked on the basis of the option they fill in the
