Each chapter includes:

• Questions for understanding the theory.
• Basic solved exercises, covering all possible cases that may be asked in exams.
• Topics for answering, including:
• practice exercises,
• theory-critical questions,
• multiple-choice questions (the 1st topic of the exams)
• open-ended questions (the 2nd topic of the exams)
• exercises (the 3rd topic of the exams)
• problems (the 4th topic of the exams).

The student should focus particularly on the open-ended questions (the 2nd topic of the exams). With these questions, they will understand the "fine" points of each chapter's material and it is a first-class practice for the exercises and problems they will solve later on.

At the end of the book, there are answers for all the topics to be answered.
