SapiX Grade 6 Kaisei Prep This is a collection of worksheets featuring problems unique to Kaisei, often referred to as "Tokyo-area problems." 1-11, no missing numbers With answers, no writing Used in the 2024 academic year I purchased this for the entrance exam but did not use it, so I am offering it at a low price. It was unopened, but I opened it to take photos. There is no writing, and it is clean, but it has been stored at home. Kaisei Prep, Saturday Special Training, Sunday Special Training, SSKA, WSKA
