This is a set of 25 designated textbooks for obtaining a primary school teaching certificate at Bukkyo University. I wasn't particularly good at studying myself, and I had a gap in my knowledge, so I was very worried. That's why I bought them as a set on Mercari. The textbooks may vary slightly depending on the year, but since the test questions and educational issues for 2025 haven't changed, I was able to obtain the credits using the old editions. In fact, the old editions were easier to understand. I purchased these used, so there is some dirt and writing, but there are markings on important parts and answers to reports and tests, which was helpful (lol). Since these are used items, they are sold as-is with no returns. Please note that "Introduction to Art Education (Old Edition)" will be changed to "Introduction to Elementary School English Content (New Edition, no cover)."
