【Brand New, Unused】 "Official Problem Collection for Statistical Investigator and Certified Statistical Investigator, Officially Certified by the Japan Statistical Society, 2017-2019" Japan Statistical Society Price: ¥2800 + tax I purchased this new, but I gave up on taking the exam, so it's unused. I kept it at home with a cover on it. However, since it's been stored at home by a private individual, please refrain from purchasing if you are overly concerned about its condition.
