This is a set of Japanese history reference books. I was dedicated to Japanese history, so my deviation score was always in the 70s. Especially with the question-and-answer book, I've made a lot of notes on what I thought was important while solving mock exams and past papers, so I think it will be very helpful. As for a recommended study schedule: If you've decided on a private university, use the time for subjects you don't need to study for your target university to study the subjects you do need. (This applies to second-year high school students as well.) For reference, in my case: Sophomore Year: 1 round of 4 "Jikkyo Chukei" books → Read textbooks and sourcebooks → 1 round of source collection → Question and answer, Hyomondai Junior Year: 1 round of 4 "Jikkyo Chukei" books → 100 questions → Waseda Japanese History → Other thematic history, chronological memorization → Waseda entrance exam preparation problem set → Past papers I studied using this route. Thank you.
