A set including a mock exam and past question collection, a basic textbook, and a quick-study DVD for the Real Estate Transaction Specialist (Takken Shi) exam. I am selling this set because I successfully passed the exam after studying for 3 months using it. The 2025 edition, consisting of two books, is intact and has not been separated. There are no markings or writing. The 2024 edition, consisting of two books, has been separated, but there are no markings or writing. The 2018 & 2023 editions, consisting of four books, have some faint pencil marks. Please understand that these are used items before purchasing. Thank you for looking.
