This book is a comprehensive aid for students of the Humanities Orientation Group of the 3rd Lyceum, as well as a useful guide for teachers who will be called upon to teach the History course. Thanks to its completeness, the validity of its content, and its methodical development, it ensures students' success in the Panhellenic Examinations.

It is organized into chapters and sections according to the structure of the school textbook.
Specifically, each section includes:
- Presentation of the key points of the lesson
- Interpretation of historical terms and analysis of conceptually complex excerpts
- Development questions with their answers
- Commentary with question-answer on all historical sources in the school textbook (so that the student can practically practice drafting the correct answer, indicating in the source approach which part of the answer is drawn from the narrative of the school textbook, which from the source, while also showing the critical comments that may be required for the completion of the answer)
- Commentary with question-answer on supplementary sources

At the end of each chapter, recapitulatory development questions are provided with their answers, closed-type questions, and evaluation criteria.

The book is supplemented with two appendices. The first appendix provides a detailed guide (with specific examples) on how to deal with sources in examinations, combinational development questions (for quick review), and evaluation criteria for the entire material. The second appendix provides answers to the closed-type questions and all evaluation criteria.
