Teaching methods

Frontal lessons.

Attendance to learning activities is mandatory.

The minimum attendance requirement to be admitted to the final exam is 66% of lessons. The 66% attendance requirement refers to the total amount of Integrated Courses lessons.

Students who fail to meet the minimum attendance requirement will not be admitted to the final exam of the course, and will have to attend relevant classes again during the next academic year.

Assessment methods

The learning assessment for this module is conducted through a final written multiple choice exam.

The questions at the end of each chapter of the Nutrition textbook are a good example of the kind of questions that will be proposed.


Gastrointestinal System, Nutrition, and Metabolism Written exam

Time available: 1 hour

15 questions multiple choice for Physiology

15 questions multiple choice for Nutrition

12 questions multiple choice plus one open question for Semeiotic


For Physiology and Nutrition

+1 correct answer.

0 unanswered question.

-0.25 wrong answer.

Minimum score needed to pass Physiology and Nutrition in each section is 8.2/15

For Semeiotic

+0.5 correct answer.

0 unanswered question.

-0.125 wrong answer.

Between 0 and +1.5 for the answer to the open question.

Minimum score needed to pass Semeiotic is 4.1/7.5

To pass the written exam the students need to pass each section.

Total score is obtained as:

[(Physio. Score + Nut Score + Sem. Score)/37.5]*33

32 or above is 30 Lode (cum Laude)

All other scores are approximated to the lower value: e.g. 25.9 = 25

Final Score

The vote obtained at the oral exam will be weighted with the vote obtained at the written exam according to the credit (5 CFU for the written part and 4 CFU for the oral part):

(Written Score *5/9) + (oral score*4/9)

30 Lode obtained at the written exam is considered 32.
