The primary goal of this book is to enrich and expand upon the topics presented in the school textbook.
The vast majority of sources come from works of contemporary and very recent historiography and bibliography, as well as reference works in the academic historical community. Additionally, historical sources are drawn and utilized from the Teacher's Book, the evaluation criteria for the History of the 3rd Grade of Lyceum (KEE), the digital material of historical sources for Modern and Contemporary Greek History from the KEG, and the Learning Objects of "Photodendro". Finally, primary archival material is often cited, as well as sources and questions from all previous Panhellenic Examination topics (1999-2020).

The structure of this aid is based on the most recent guidelines for the examination method of the subject. The aid begins with a brief overview of historiographical currents in the science of History. This is followed by a useful guide for the methodological approach and analysis of historical sources, whether they are textual sources (published or unpublished) or multimodal texts (photographs, cartoons, statistical tables, diagrams, etc.). The aid includes the chapters and sections of the school textbook that belong to the examined material. Each section consists of a brief outline, the definitions that arise in the section, comprehension questions (development), closed-type questions (T/F), commentary on the most important images of the school textbook, analysis of the school textbook sources, and examination of additional sources as historical information for a more complete, detailed, and exhaustive understanding of the historical narrative.

Each chapter is framed at the end with combinatory questions corresponding to the specific chapter and five review evaluation criteria. At the end of the book, a chronological table with the most important dates and events of the historical narrative is provided.
