40 Leaves Exercise Book - 20pcs Pack

Exercise books may act as a primary record of students' learning efforts. For younger pupils, books are often collected at the end of each lesson for review, scoring, or grading. Loose worksheets may be pasted into the book so that they are bound with other work. The papers in a composition book often have the baseline and cap line printed in blue to aid writing, with a (sometimes red) vertical line for a margin on the left hand of every page. 

Traditionally, the inside back cover contains a table of the weights and measures of the English (imperial) system printed for reference; however, this feature has become less common in countries that have adopted the metric system. Sometimes a multiplication table, or grammar or punctuation tips, are also found on the inside back cover. The inside front cover typically has a place to put one's weekly class schedule.

Composition books are traditionally bound through the fold—that is, the pages are folded, and stitched vertically along the fold. This allows to open them completely flat, simplifying writing on the left side, and also makes them significantly more durable than loose leaf pads or spiral notebooks.

Exercise books with fewer sheets, such as Blue books, are used in many post-secondary schools during assessment tests.
