A seat marked with Reg. No. will be alloted to each student. The student should ensure that he/sheoccupies the correct seat only. If any student is found to have occupied the seat of another student,both the students shall be removed from the examination and shall have to accept any other penaltyimposed upon them.
Student can not use log tables and calculators or any other material in the examination hall.
Student must abide by the instructions issued during the examination, by the invigilators or thecentre incharge.
Before attempting the question paper ensure that it contains all the pages and that no question ismissing.
