Judicial Examination/Preliminary Examination Agaloot Academy This is an official USB drive containing explanation videos for all 7 subjects of the Important Problem Acquisition Course, released by the official source. Currently, it is no longer sold by the official source, so I believe it is a rare item. The list price was probably around 100,000 yen. The video explanations by lecturer Hokuto Kudo will deepen your understanding of the content, unlike simply listening to the audio.
