Thank you for viewing this item among many similar products. Although this book is old, with its first edition in 2020, this is not a fundamental problem for studying. Even if you were to use the latest reference books, would you be guaranteed to pass? Of course not. This is because the difficulty of university entrance exams has not changed at all compared to five years ago. Although the title says "Basic," the example problems included are not just textbook level. Let's cultivate the "basic" skills to handle university entrance exam questions with this book. And then, let's build upon that foundation to improve your practical and applied skills! There are no writings, markings, or highlighting. Thank you.
