This is a problem set for the five subjects of high school entrance exams. It covers a wide range of topics and can be used for solidifying your basics, identifying your weaknesses, and practicing for the final check. I was doing the exercises on separate sheets from the middle, but I did write on the social studies sections 01.02, so I would appreciate your understanding (see photo 5). Also, I have marked various pages with symbols like those in photo 4. (×... I can solve it, \ ... I'm worried, (no mark) ... I can't solve it, difficult, are the criteria for the marks.) I hope we can do business!
