Workbook collecting questions on the high school entrance examination = 1080 yen ($10.19 €7.88)

My daughter will take a high school entrance examination next February. To prepare for it, I bought a workbook which collects past tests of the entrance examinations. The book is for the entrance examination of Tokyo metropolitan high schools. It cost 1080 yen ($10.19 €7.88). The workbook has questions on the entrance examinations in past seven years. We can see the trend of questions in the book.
At the examination, students take 5 subjects; Japanese, Math, Social studies (History, Geography and so on), Science, and English.
In Tokyo, the result of entrance examination depends on the test score and the evaluation score in the junior high school. The ratio of test score and the evaluation score is 7:3.
