The first goal of this book is the enrichment and expansion of the topics presented in the textbook. The large number of sources comes from works of contemporary and very recent historiography and bibliography, as well as reference works in the academic historical community. In addition, historical sources are drawn and used from the teacher's Book, from the evaluation criteria for the History of the 3rd Lyceum (KEE), from the digital material of historical sources for the Modern and Modern Greek History of the KEG, from the Learning Objects of " Phototree". Finally, primary archival material is often cited, as well as the sources and questions from all previous issues of the Hellenic Examinations (1999-2020).

The way in which this aid has been structured is based on the most recent guidelines for how to examine the course. The aid begins with a brief overview of the historiographic currents in the science of History. Here is a useful guide to the methodological approach and analysis of historical sources, whether they are textual sources (published or unpublished) or multimodal texts (photographs, cartoons, statistical tables, diagrams, etc.).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 help includes the chapters and sections of the textbook that belong to the examined material. Each section consists of a brief outline, the definitions that arise in the section, comprehension (developmental) questions, closed-type questions (S/L), commentary on the most important images in the textbook, analysis of textbook sources, and citation with examination of additional sources , as historical information for a fuller, more detailed and exhaustive understanding of the historical narrative.

Each chapter is framed at the end with combination questions that correspond to the specific chapter and five repetitive evaluation criteria. At the end of the book, a chronological table is offered with the most important dates and events of the historical narrative.
