The course is divided into lessons (on the blackboard, supplemented by transparencies) and exercises on the blackboard.
During the lessons the main results, their scope of validity, the mutual relations, and the most relevant applications are presented and discussed.
The exercises are aimed at acquiring the main calculation techniques and the most elaborate strategies for solving problems, in the context of the theoretical results already acquired. Part of the exercises is also addressed to the solution of the written exams of the previous years.

The exam consists of a written examination and an optional oral examination: the written examination is further divided into two parts: exercises (first part) and theoretical questions (second part). Written and optional oral examinations must be passed within the same session. The oral examination is based on definitions, examples and counterexamples, theorems (some with proofs).
