My teaching journey in the subject of Biology was accompanied from the beginning by the belief that "students always love learning Biology". My many years of teaching experience turned this belief into a conviction.

Students always love learning Biology, and we, the educators, must contribute with every educational means towards this goal.

This book aims to meet the special needs of students who have completed the study of the examinable material of Orientation Biology, have understood the cognitive subjects that this material processes, and are preparing for their review.

To this end, the book contains:
- Combined questions with answers, covering all the examinable material
- Methodology of combined exercises
- Model solved exercises with full justification
- Review exercises of graded difficulty divided into topics A, B, C, and D as in the Panhellenic Examinations
- Answers to all exercises
