Thank you for viewing. This is a textbook set including the problem section of the Cutting Edge Blue series, a writing notebook, and an answer key with explanations. Since I used printed materials in class, there are no writings in this set. The level of this book allows you to prepare for a wide range of universities, from local national and public universities to prestigious private universities and former imperial universities. Also, the explanation book carefully explains the sentence structure for each sentence. Highly recommended.
