INSTRUCTIONS TO CANDIDATES FOR ANSWERING ON THE OMR ANSWER SHEET
Use only HB Pencil to mark the Ovals in the Answer Sheet.
Use Ball Point Pen to fill the Boxes (ie for the Question Booklet No., Roll Number, Date of Birth and Signature.)
Indicate the Question Booklet Series and Question Booklet Serial Number in the space provided on the OMR Answer Sheet without fail.
Please mark the relevant Ovals against the columns like Series, Category, Quota and Main Branch of Engineering as applicable to you.
Mark your answer only in the appropriate space against the Number corresponding to the question you are answering. Darken the response for each question:
A B C D
(ie., if the answer to the Question is option A , then it needs to be darkened )
6. Please ensure that the Ovals are completely darkened.
In case of any mistake while marking, please erase the mark completely and fill the correct Oval again. Do not leave stray marks/half filled Ovals on the Answer Sheet.
Rough work must not be done on the Answer Sheet. Use the blank pages given at the end of the Question Booklet for rough work
