Type of Assessment
Single exam, oral; the student will be called to answer some questions about the contents of the course; evaluation will cover knowledge of arguments, ability to make connections between them and critical capabilities. During the exam, students will be allowed to peruse a printed document, including the most complex and/or less important mathematical formulas
