"[2024 Edition] The Easiest IT Passport Textbook for Guaranteed Success + Practice Questions by Order of Appearance" Keisuke Takahashi Price: ¥1600 I used it while trying to keep it in as clean a condition as possible. There are no folds, writings, or stains, so I think you can use it without any problems :) I will also include the red sheet. #KeisukeTakahashi #IT #ITPassport #Certification #KeisukeTakahashi #Takahashi_Keisuke #Book #Electrical/Mechanical/ElectronicCommunication"
