Features:

• The theory is presented using the question-and-answer method. Where necessary, additional information is provided to clarify fine points of the theory. At the end of the theory of each chapter, there are questions for review.
• The questions are structured by type (closed type - topic 1 of National Exams and open type - topic 2 of National Exams). Specifically, closed type questions are divided into group A questions (based on the school book theory) and group B questions (in-depth questions).
• In the solved exercises - problems of each chapter, the methodology is integrated into key points, which the student often encounters while solving exercises and problems. There is also detailed guidance on what the student should not forget after studying the solved example, as well as a note on which exercises to solve are similar for practice.
• The exercises to be solved contain basic concepts that the student needs to grasp before moving on to the problems to be solved, which require more complex thinking.
• In each section (before the closed type questions), there is a detailed study proposal at two levels. The 1st level refers to basic study, while the 2nd level refers to in-depth study.

For all questions, exercises, and problems to be solved, there are detailed solutions at the end of the book.
