                             INSTRUCTIONS FOR CANDIDATES
1.   IMMEDIATELY AFTER THE COMMENCEMENT OF THE EXAMINATION, YOU SHOULD CHECK THAT
     THIS QUESTION BOOKLET DOES NOT HAVE ANY UNPRINTED OR TORN OR MISSING PAGES OR
     QUESTIONS ETC. IF SO, GET IT REPLACED BY A COMPLETE QUESTION BOOKLET.
2.   Please note that it is the candidate’s responsibility to encode and fill in the Roll Number and
     Question Booklet Series Code A, B, C or D carefully and without any omission or discrepancy at
     the appropriate places in the OMR Answer Sheet. Any omission/discrepancy will render the
     OMR Answer Sheet liable for rejection.
3.   This Question Booklet contains 100 questions. Each question is printed in English only. Each
     question comprises four responses (answers). You will select the response which you want to
     mark on the OMR Answer Sheet. In case you feel that there is more than one correct response,
     mark the response which you consider the best. In any case, choose ONLY ONE response for
     each question.
4.   You have to mark all your responses ONLY on the separate OMR Answer Sheet provided. See
     Instructions at the backside of the OMR Answer Sheet.
5.   All questions carry equal marks.
6.   Before you proceed to mark in the OMR Answer Sheet the response to various questions in the
     Question Booklet, you have to fill in some particulars in the OMR Answer Sheet as per
     instructions mentioned on the OMR Answer Sheet.
7.   After you have completed filling in all your responses on the OMR Answer Sheet and the
     examination has concluded, you should hand over to the Invigilator only the OMR Answer
     Sheet. You are permitted to take away with you the Question Booklet, along with candidate’s
     copy of OMR Answer Sheet.
8.   Sheets for rough work are appended in the Question Booklet at the end.
9.   Penalty for wrong answers :
     THERE WILL BE PENALTY FOR WRONG ANSWERS MARKED BY A CANDIDATE AS UNDER.
       (i) There are four alternatives for the answer to every question. For each question for which
           a wrong answer has been given by the candidate, 0.25 mark assigned to that question will
           be deducted as penalty.
      (ii) If a candidate gives more than one answer, it will be treated as a wrong answer even if one
           of the given answers happens to be correct and there will be same penalty as above to that
           question.
     (iii) If a question is left blank, i.e., no answer is given by the candidate, there will be no penalty
           for that question.
