Teaching languages


  • Catalan

This subject has been successfully enrolled by a number of foreign students, most of them from Italy. Classes are taught in Catalan and students are expected to have a basic understanding of spoken Catalan. However, exams and practical reports can be written in Italian or in other languages. Public questions in the classroom and private questions to the teacher can also be asked in Italian or other languages.

Skills


Specific skills
  • CE4: Understand and apply the principles of basic knowledge of general chemistry, organic and inorganic chemistry and their applications in engineering.

Evaluation system


Questionnaire on the scientific method: 10%

Radioactivity questionnaire: 10%

First partial test: 40%

Second partial test: 40%

Recovery exam: 80%

For students who do not pass the assessment during the course, 20% of the grade of the questionnaires will be maintained, and an overall retake exam will be held which will be worth 80% of the grade. In this case, the final grade of the course will be a maximum of 5.

The questionnaire on the scientific method must be delivered on time on the set date.

The radioactivity questionnaire will be accepted even if it is delivered out of time, with a penalty on its qualification.
