While writing an article about medical school entrance exam cram schools, I interviewed Ms. Yui Kashihara (19 years old, entered medical school of national university), the developer of the memorization tool "Ebbinghaus Fusen".

Sengi focused on the use of Ebbinghaus Fusen from a parent's perspective. She plans to share this information with educators as a reference for "how to memorize my child from a parent's perspective" in the junior high school entrance examination market, where the memorization status of a child can be easily monitored by the date on the sticky note.

The type with 2 perforations is not suitable for carrying around. (non-portable) We recommend to use the perforated type by putting it on a test, etc. and putting it in a clear book. The non-perforated type is suitable for carrying around. When carrying it around, it is recommended to stick it so that only one review day is visible.
