Through various types of writing problems, you can naturally practice the grammar you've learned in sentences and writing, and further build the foundation for writing in English on your own.

* Actual Test
The internal exam questions are organized into a total of 35 questions per chapter to ensure sufficient practice.
In particular, the proportion of frequently appearing types of questions and descriptive questions has been increased recently, enabling effective preparation for internal exams.
You can check the main multiple choice questions by solving the problems by marking them as 'frequently appearing' and 'difficulty level'.

* Descriptive Master
You can prepare for the descriptive questions in school exams by studying 10 questions per session.

* Workbook
By repeatedly studying a sufficient amount of writing/descriptive problems that are slightly more difficult than those in the main book, students can acquire the contents of the main book.
Additionally, the chapter test is designed to conclude each unit by solving the internal exam questions once more.
