Wasted efforts

Why must I write the frikkin Lab Manual/file if the only thing we do in it is copy from the book ? Won't it be easier if I just write the relevent page numbers (from the book) along with the observations ? Or rather submit a xerox of the book ?
Never got the point why we make this stupid thing , in the school ... and I'll never get it in the college ...
Why must I make this f***ing thing ?
Oh yes .. the marks ... !@#$%^&*&^%$#@! !@#$ !@#$%^
