This book is the new, advanced proposal I present for the Mathematics Orientation of the 12th Grade.

In its two volumes, the entire material is structured into sixty lessons. In each of these, there is a detailed presentation of the theory with simple examples – and sometimes counterexamples – for its complete understanding. Then, model solved exercises, methodology, comments, and key notes follow.

The unsolved exercises are presented in the same order as the solved ones. In fact, many of them refer to corresponding solved exercises, which will be useful for students. The exercises are grouped based on the criterion of easy search and access to all their forms.

The rich subject matter guarantees the completeness of the book, while a selected part of it, highlighted with appropriate symbols, ensures its usability and constitutes the author's study proposal. At the end of each lesson, there is a forty-minute assessment criterion. Additionally, there are combined review topics and three-hour exams for students of all levels.
