Any student found/reported using unfair means to improve his/her performance in the test, shall be disqualified from STaRT2013. B. How to fill Objective Response Sheet (ORS) for filling details marking answers: 9. Use only HB Pencil/Blue or Black ball point pen for filling the ORS. Do not use Gel/Ink/Felt pen as it might smudge the ORS. 10. Write your STaRT-2013 Student Registration No. in the boxes given at the top left corner of your ORS with blue/black ball point pen. Also, darken the corresponding bubbles with HB Pencil/Blue or Black ball point pen only. 11. If any student does not fill his/her STaRT-2013 Student Registration No. correctly and properly, then his/her ORS will not be checked/ evaluated. 12. Since it is not possible to erase and correct pen filled bubble, you are advised to be extremely careful while darken the bubble corresponding to your answer. 13. Neither try to erase / rub / scratch the option nor make the Cross (X) mark on the option once filled. Do not scribble, smudge, cut, tear, or wrinkle the ORS.
