There are many students who have spent their precious time behind this; their hard work is really apreciatble.This reference text consist of many subjects related earth, human being etc...
It is sure that this text book will be useful for all students in their assignments, projects etc. Basically these are the works done by each classes of seven to ten .They were divided into separate groups and given particular subjects This made a very good competitive attitude among them. So that all the teams, have tried their best for collecting sources .We hope that this will be an asset for the school library.
