Exam mode
Student performance will be assessed through a written examination and an oral examination.
The written exam, which lasts three hours, requires students to solve problems—possibly involving numerical calculations—related to momentum, mass, and heat transport, using both local and macroscopic approaches.
The purpose of the written exam is to evaluate the student's ability to work independently by integrating the knowledge acquired during the course and applying it to the solution of problems that, while similar to those discussed in class, are not repetitive.
A minimum threshold (which may be below 18/30) is required in the written exam in order to be admitted to the oral exam.
The written exam may be replaced by midterm tests administered during the lecture period.
The oral exam may include both theoretical questions and problem-solving tasks. It is designed to assess the student's understanding of the theoretical foundations of the course, their ability to identify appropriate problem-solving strategies, and their capacity for critical reasoning about the methods used and the results obtained.
The final grade is determined based on the combined performance in both the written and oral examinations.
