After attempting a question, if candidate wants to change his/her answer, erase com- pletely to change the response and re-dark another circle.
Marking of answer other than darkening shall be cancelled and darkening should remain within the circle or otherwise computer shall not accept during evaluation of answer-script.
Rough work must not be done on the answer sheet. Use the blank space given in the Test Booklet for this purpose.
Candidate is to hand over both the Test Booklet and Answer sheet to the Invigilator before leaving the Examination Hall.
