Economic science is a vibrant field that deals with many of the issues affecting our daily lives. Of course, it is not a subject that a student can learn well only by reading. However, through exercises, one can discover that this science "comes to life" as they begin to see for themselves how it works in practice. This book aims to thoroughly prepare candidates in the scientific field of Economics and Informatics for the Panhellenic exams. Its main part includes all the topics that have been set in the exams over the years, categorized by chapter for better and more effective use. At the same time, selected exercises and questions that have not been used in the exams so far have been added.

An important part of the book is the Answers section, where emphasis has been placed on clear explanations and answers, especially on topics where students often encounter difficulties. Finally, the review tests (Assessment Criteria) at the end of each chapter help to thoroughly consolidate what has been taught.
Special thanks are due to fellow Professors Mr. Christos Terzopoulos, Efi Dimopoulou, Haris Kariophylla, and George Asimakopoulos, who willingly agreed to review individual chapters of this book.
