The idea of this book was created when we needed to prepare our biology students for the national exams. When we asked our students to review, as all students need to do from time to time, we faced the question: "Dad, where do I start? We have written so many notebooks. How will I catch up?" So, we had to create a revision guide 1-1. Of course, Mathematics is not recipes but thinking. However, in the special conditions of the national exams, the student needs guidance even in revision, so that they can gain the confidence that they know the basic points of the curriculum. There is also the possibility for the student to revise specific sections of the curriculum in which they feel they are lacking, as this book is divided into sections following the progression with which the curriculum of the national exams is taught. This book comes to meet this need for revision.
