stated otherwise.
2. The test is of 3 hours duration and the Test Booklet contains 180 multiple-choice questions (four options with a
single correct answer) from Physics, Chemistry and Biology (Botany and Zoology).
3. 45 questions in each subject. (a) Questions in each subject, Physics - (Question Nos – 1 to 45), Chemistry – (Ques-
tion Nos – 46 to 90), Biology: Botany – (Question Nos – 91 to 135), Zoology – (Question Nos – 136 to 180). All the
questions are compulsory.
4. 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 maximum marks are 720.
5. Use Blue/Black Ball Point Pen only for writing particulars on this page/marking responses on Answer Sheet.
6. Completely darken/shade the relevant circle with a blue or black ink ballpoint pen against the question number on
the OMR answer sheet.
7. Use the space provided on each page of the question booklet for Rough Work. Do not use the OMR answer sheet for
the same.
8. Use of Electronic/Manual Calculator is prohibited.
9. Hand over the OMR answer sheet to the room invigilator as it is.
10. After separating the top sheet(office copy), the invigilator will return the bottom sheet replica (Candidate’s copy) to
you.
