However, unofficial versions do exist.

Kumon’s philosophy is "self-learning." If a student gets stuck on Problem 45, they are supposed to review the example problems. However, Level I examples are sparse. When a student tries 4x^2 + 12x + 9 and gets (2x + 3)(2x + 3) but the answer says (2x+3)^2 , the student needs to see why their distribution was correct but their notation was sloppy. The solution book provides that instant visual feedback. Kumon Level I Math Solution Book
