New Education Series, Complete 20-Book Set ^^ This is a set of textbooks and other materials purchased and used during my schooling to obtain a childcare worker's license. I graduated from school from October 2023 to September 2025. I have used highlighters and ballpoint pens to write in them. As someone with no prior experience in childcare, the material was very difficult, but I have written in all the important parts as indicated by the instructors, and I have also written down important things I heard, so I think it will be easy to understand for those who are going to study from now on. ☆I graduated this year, so I think it will still be helpful, but please refrain from purchasing if you are concerned about the condition☆ ※Please refrain from purchasing if you are concerned, as there are writings in the textbooks, etc.^_^ You can purchase from one book!!
