You are clearly advised in the OMR sheet to fill it with a black pen. Please do not use a pencil on the OMR sheet as sometimes the pencil is unable to fill the circle completely making it difficult for the computer to read it. Hence, your answer might be discarded. Hence please carry a black ball pen for the filling of the OMR SHEET. All the best for the exam.

Hello Goutham,

OMR is genrally filled using a black or blue ball point pen, however you may also use a pencil to avoid any wrong markings, but before submitting make sure the marks are easily scannable by the scanner. You may confirm with the examiner, keep a black/blue ball point pen with you.

Hope this Helps

Regards
