The term "ladder" derives from the multi-variant structure of the book. It usually features multiple variants of identical difficulty levels (e.g., Variant 1, Variant 2, Variant 3, and Variant 4). This allows teachers to distribute different variants to adjacent students to prevent copying, or use them for repeated testing and correction of mistakes. 3.
