Kumon: The Shared Trauma of a Generation.

TikTok users are sharing their traumatic experiences with Kumon, a worksheet-based study program designed to help children improve their math and reading skills. While some people credit the program with improving their skills, many others describe it as the "biggest trauma of their life" and say it left a lasting negative impression. Some even say their parents would "threaten" them with Kumon worksheets or force them to do them on vacation.
