Read the following instructions carefully before you begin to answer the questions.
IMPORTANT INSTRUCTIONS
1. The applicant willbe supplied with Question Booklet 15minutes beforecommencementof the examination.
2. This Question Booklet contains 200 questions. Prior to attempting to answer, the candidates are
requested to check whether all the questions are there in series and ensure there are no blank pages in
the question booklet. In case any defect in the Question Paper is noticed, it shall be reported to
the Invigilator within first 10 minutes and get it replaced with a complete Question Booklet.
If any defect is noticed in the Question Booklet after the commencement of examination, it
will not be replaced.
3. Answer all questions. All questions carry equal marks.
4. You must write your Register Number in the space provided on the top right side of this page. Do not
write anything else on the Question Booklet.
5. An answer sheet will be supplied to you, separately by the Room Invigilator to mark the answers.
6. You will also encode your Question Booklet Number with Blue or Black ink Ball point pen in the space
provided on the side 2 of the Answer Sheet. If you do not encode properly or fail to encode the above
information, action will be taken as per Commission's notification.
7. Each question comprises [our responses (A), (B), (C) and (D). You are to select ONLY ONE correct
response and mark in your Answer Sheet. In case you feel that there are more than one correct
response, mark the response which you consider the best. In any case, choose ONLY ONE response for
each question. Your total marks will depend on the number of correct responses marked by you in the
Answer Sheet.
8. In the Answer Sheet there are four circles @ '@' @ and @ against each question. To answer the
questions you are to mark with Blue or Black ink Ball point pen ONLY ONE circle of your choice for
each question. Select one response for each question in the Question Booklet and mark in the Answer
Sheet. If you mark more than one answer for one question, the answer will be treated as wrong. e.g. If
for any .item, @ is the correct answer, you have to mark as follows:
0.@@
9. You should not remove or tear off any sheet from this Question Booklet. You are not allowed to take
this Question Booklet and the Answer Sheet out of the Examination Hall during the time of
examination. After the examination is concluded. you must hand over your Answer Sheet to the
Invigilator. You are allowed to take the Question Booklet with you only after the Examination is over.
10. Do not make any marking in the question booklet except in the sheet before the last page of
the question booklet, which can be used for rough work. This should be strictly adhered.
11. Applicants have to write and shade the total number of answer fields left blank on the boxes provided
at side 2 of OMR Answer Sheet. An extra time of 5 minutes will be given to specify the number of
answer fields left blank.
12. Failure to comply with any of the above instructions will render you liable to such action or penalty as
the Commission may decide at their discretion.
