  The Cons (Why Kumon centers discourage it)

  1. The "Cheat Sheet" Problem: Students are clever. If the answer book is left on the kitchen table, they will copy answers. This destroys the entire purpose of Kumon, which is to build calculation stamina through repetition.
  2. Masking the Gap: If a student gets an answer wrong, circles it, and then copies the correct answer from the back of the book without re-doing the work, they haven't learned the regrouping process. They will fail the Level B "Achievement Test."
  3. Dependency: Students who rely on the answer key stop developing self-correction skills.
