LESSONS START

The third week of September.

## EXAMS

Exam description

The examination consists of a written part and an oral discussion. The written part is made up of 10 questions that cover all the material of the course.

The use of notes, books, or electronic devices is forbidden.

Assessment methods

The questions of the written part will verify both the operational skills through problem solving and the learning of the theory, such as definitions and theorems. During the oral test there will be a discussion about the written part and two to three additional questions.
