Important Instructions :
1. Immediately fill in the particulars on this page of the Test
Booklet with Blue/Black Ball Point Pen. Use of pencil is strictly
prohibited.
2. The Answer Sheet is kept inside this Test Booklet. When you
are directed to open the Test Booklet, take out the Answer
Sheet and fill in the particulars carefully.
3. The test is of 3 hours duration.
4. The Test Booklet consists of 90 questions. The maximum
marks are 360.
5. There are three parts in the question paper A, B, C
consisting of Physics, Mathematics and Chemistry having
30 questions in each part of equal weightage. Each question
is allotted 4 (four) marks for correct response.
6. Candidates will be awarded marks as stated above in instruction
No. 5 for correct response of each question. ¼ (one fourth) marks
will be deducted for indicating incorrect response of each question.
No deduction from the total score will be made if no response is
indicated for an item in the answer sheet.
7. There is only one correct response for each question. Filling
up more than one response in any question will be treated as
wrong response and marks for wrong response will be
deducted accordingly as per instruction 6 above.
8. Use Blue/Black Ball Point Pen only for writing particulars/
marking responses on Side-1 and Side–2 of the Answer Sheet.
Use of pencil is strictly prohibited.
9. No candidate is allowed to carry any textual material, printed
or written, bits of papers, pager, mobile phone, any electronic
device, etc. except the Admit Card inside the examination
room/hall.
10. Rough work is to be done on the space provided for this
purpose in the Test Booklet only. This space is given at the
bottom of each page and in one page (i.e. Page 39) at the end
of the booklet.
11. On completion of the test, the candidate must hand over the
Answer Sheet to the Invigilator on duty in the Room/Hall.
However, the candidates are allowed to take away this Test
Booklet with them.
12. The CODE for this Booklet is D. Make sure that the CODE
printed on Side–2 of the Answer Sheet and also tally the
serial number of the Test Booklet and Answer Sheet are the
same as that on this booklet. In case of discrepancy, the
candidate should immediately report the matter to the
Invigilator for replacement of both the Test Booklet and the
Answer Sheet.
13. Do not fold or make any stray mark on the Answer Sheet.

40. Read the following instructions carefully :
1. The candidates should fill in the required particulars
on the Test Booklet and Answer Sheet (Side–1) with
Blue/Black Ball Point Pen.
2. For writing/marking particulars on Side–2 of the
Answer Sheet, use Blue/Black Ball Point Pen only.
3. The candidates should not write their Roll Numbers
anywhere else (except in the specified space) on the
Test Booklet/Answer Sheet.
4. Out of the four options given for each question, only
one option is the correct answer.
5. For each incorrect response, one–fourth (¼) of the total
marks allotted to the question would be deducted from
the total score. No deduction from the total score,
however, will be made if no response is indicated for
an item in the Answer Sheet.
6. Handle the Test Booklet and Answer Sheet with care,
as under no circumstances (except for discrepancy in
Test Booklet Code and Answer Sheet Code), another set
will be provided.
7. The candidates are not allowed to do any rough work
or writing work on the Answer Sheet. All calculations/
writing work are to be done in the space provided for
this purpose in the Test Booklet itself, marked ‘Space
for Rough Work’. This space is given at the bottom of
each page and in one page (i.e. Page 39) at the end of
the booklet.
8. On completion of the test, the candidates must hand
over the Answer Sheet to the Invigilator on duty in the
Room/Hall. However, the candidates are allowed to
take away this Test Booklet with them.
9. Each candidate must show on demand his/her Admit
Card to the Invigilator.
10. No candidate, without special permission of the
Superintendent or Invigilator, should leave his/her
seat.
11. The candidates should not leave the Examination Hall
without handing over their Answer Sheet to the
Invigilator on duty and sign the Attendance Sheet
again. Cases where a candidate has not signed the
Attendance Sheet second time will be deemed not to
have handed over the Answer Sheet and dealt with as
an unfair means case. The candidates are also required
to put their left hand THUMB impression in the space
provided in the Attendance Sheet.
12. Use of Electronic/Manual Calculator and any
Electronic device like mobile phone, pager etc. is
prohibited.
13. The candidates are governed by all Rules and
Regulations of the JAB/Board with regard to their
conduct in the Examination Hall. All cases of unfair
means will be dealt with as per Rules and Regulations
of the JAB/Board.
14. No part of the Test Booklet and Answer Sheet shall be
detached under any circumstances.
15. Candidates are not allowed to carry any textual
material, printed or written, bits of papers, pager,
mobile phone, electronic device or any other material
except the Admit Card inside the examination
room/hall.
