Do not open this Test Booklet until you are asked to do so.
Important Instructions :
1. The Answer Sheet is inside this Test Booklet. When you are directed to open the Test Booklet, take out the
Answer Sheet and fill in the particulars on OFFICE Copy carefully with blue/black ball point pen only.
2. The test is of 3 hours & 20 Minutes duration and the Test Booklet contains 200 multiple-choice questions
(four options with a single correct answer) from Physics, Chemistry and Biology (Botany and Zoology). 50
questions in each subject are divided into two Sections (A and B) as per details given below :
(a) Section A shall consist of 35 (Thirty-five) Questions in each subject (Question Nos - 1 to 35,51 to 85,

(b) Section B shall consist of 15 (Fifteen) questions in each subject (Question Nos- 36 to 50, 86 to 100,
136 to 150 and 186 to 200). In Section B, a candidate needs to attempt any 10 (Ten) questions out of
15 (Fifteen) in each subject.
Candidates are advised to read all 15 questions in each subject of Section B before they start attempting the
question paper. In the event of a candidate attempting more than ten questions, the first ten questions answered
by the candidate shall be evaluated.
3. Each question carries 4 marks. For each correct response, the candidate will get 4 marks. For each incorrect
response, one mark will be deducted from the total scores. The maximummarks are 720.
