Teaching methods

Lectures. Part of the lectures are dedicated to discussing and solving problems of Thermodynamics and Electromagnetism.

Assessment methods

The exam consists of a written test divided into 2 parts:

1) Theory: open questions to verify the student's ability to organize a written text on topics discussed in the class.

2) Exercises:  exercises of Termodynamics and  Electromagnetism, to test the problem-solving attitudes of the student. Both the logical path followed to get the final result and the result itself will be evaluated.

During the written exam it is not allowed the use of books and electronic devices such as laptop and tablet.It is allowed to use a calculator and a A4 paper sheet written by the student.

The dates of the exams are visible on the site of Almaesami
