Teaching methods
Class lessons and in class exercises carried out by the teacher with students.
Assessment methods and criteria
The exam can be succeeded as:
1) divided into two written examinations, at the middle and the end of the course, that complete the exam; or
2) written exam, during regular scheduled examinations.
In both cases, the exam is written and composed of multiple choice questions, open answer questions, and some exercises.
Examples of exercises are shown and solved during the course.
Other information
None.
