1. The initial 10 minutes are earmarked for the candidates to carefully read the instructions. (Note : The

candidates are not allowed to either look inside the question booklet or start answering during these

initial 10 minutes.)

2. The question booklet and answer sheet are issued separately at the start of the examination.

3. This question booklet contains 60 questions.

4. Read each question carefully.

5. Determine the correct answer, one out of the four available choices given under each question.

6. Completely darken/shade the relevant circle (with a HB pencil only) against the Question No. on the

Answer Sheet.

7. For each correct answer, three marks will be awarded. For each wrong answer, 1 mark will be deducted.

For Example

Q. 12 : In the Question Booklet is: Which one of the following is linear in Geometry ?

(Answer Sheet)

(1) SO2 Q.12. 

(2) CO2

(3) NO2

(4) KO2

Thus as the correct answer is choice 2, the candidate should darken completely (with a HB pencil) the

circle corresponding to choice 2 against Question No. 12 on the Answer Sheet. If more than one circle is

darkened for a given question such answer will be rejected.

8. Do not use white-fluid or any other rubbing material on answer sheet. No change in the answer once

marked is allowed. Before handing over the answer sheet to the invigilator, candidate should check that

Roll No. and Test-Booklet code have been filled and marked correctly.

9. Rough work should be done only on the space provided in the question booklet.

10. Immediately after the prescribed examination time is over, the Answer sheet and Question booklet

are to be returned to the invigilator. If the candidate wants to leave the examination hall before time,

he/she should hand over the question paper and answer sheet to the invigilator. However, no student can

leave the examination hall before half time.
