INSTRUCTIONS TO THE CANDIDATES
This Question Booklet is printed in two languages—Hindi and English. Candidates can select any one of the
two languages according to their convenience.
Each question has four options. There is only one correct answer to each question. Choose the appropriate
option and darken/blacken the corresponding circle on the Answer Sheet (OMR Sheet) with black point pen.
In tMs examination there are two question papers, consisting of 150 objective type questions and each question
carries 2 marks. Both the question papers and all the questions are compulsory. Two (2) marks shall be
awarded for each correct answer. Unanswered question will not be given any marks. There is no provisions
for Negative Marking.
PaperI General paper (Q. No. 1-50)
Paper n Question paper on the Subject opted by the examinee (Q. No. 51-150)
4. No. of pages consisting of this question booklet is indicated over the cover page. Candidates are advised to
ensure that all the pages of Question Booklet are properly printed and binded. Otherwise they may demand
the other Question Booklet of the same set.
5. Kindly make necessary entries on the Answer Sheet (OMR Sheet) only at the places indicated and nowhere else.
6. Examinee should do all rough work on the spaces meant for rough work on the pages given in the Question
Booklet and nowhere else, not even on the Answer Sheet (OMR Sheet).
7. If there is any sort of mistake either of printing or of factual nature in any question, then out of the Hindi and
English versions of the question, the ffindi version will be treated as standard one.
8. Use of any type of calculator, log table or any t3q>e of electronic devices etc. are not allowed.
9. Use only black ball point pen to mark the answers in the Answer Sheet (OMR Sheet) only after you are
instructed to open the Question Booklet.
10. Candidates will leave the Examination Hall only after handing over the Answer Sheet (OMR Sheet) to the
Invigilator at the end of the examination.
11. Before answering on Answer Sheet (OMR Sheet) ensure to follow the instructions given for that.
