Biology Question for Nine Standard Class

At present I am a teacher of a secondary school where I teach LIFE SCIENCE (Biology). I am doing this job along with continuing my research works. I have set the question paper for Class-IX in Life science for the first terminal examination was held in August, 2007.

I am publishing this question paper of that examination through associated content web page, to show my question style to the biology students and teachers. I hope they will have an idea about the question setting by me and also hope they will prefer it. I think question papers should be set in this standard for class-IX. Comments are welcome.

The name of the school is not mentioned for maintaining the privacy.
