The subject is composed by a 3 hours of theoretical/practical lectures, and 1 hour of optional tutoring, making a total of 4 hours per week of contact hours.

Grading

Theoretical component ($45%$)

  • A first mid-term test (T1) on a Wednesday afternoon
  • One second test (T2) on the date of the 1st exam
  • Tests are optional, but delivery of the 1st test requires the completion of the 2nd test
  • Each test counts for $50%$ of the theoretical component grade; test scores are rounded to tenths and added together to calculate the final score of the theoretical component
  • The exam, both in the Regular Season (E1) and in the Appeal (E2), counts for $100%$ of the theoretical component’s grade

Practical component ($55%$)

  • One project, carried out in groups of 2 students, worth 40% of the final grade
  • A presentation of a scientific article, performed by groups of 4 students, worth $15%$ of the final grade
  • The presentation of the article will be evaluated by faculty and peers

Final grade: weighted average of the grades of each component, rounded to the unit

  • $Final$ = $\lfloor 0.45 \times Theoretical + 0.55 \times Practical + \frac{1}{2}\rfloor$
  • $Theoretical$ = $round(max(T1 + T2, E1, E2))$
  • $Practical$ = $round(20 \times \frac{project \times 0.4 + article \times 0.15}{0.55})$
  • $T1, T2 \in [0, 10]$
  • $E1, E2, project, article \in [0, 20]$
  • $round(x) = \frac{\lfloor 10 \times x +\frac{1}{2} \rfloor}{10}$

Assessment in Appeal Period

  • An optional theoretical exam (with a weight of $45%$ in the final grade of the UC)
  • Students who took the tests can improve just one of them, or take a full exam (in either case, it never gets worse)
  • A project to be announced after the end of the Normal Period (with a weight of $55%$ in the final grade of the UC)

Penalties for late deliveries

  • The project and paper presentation will have to be delivered by a deadline
  • After this limit, the penalty will be 1 value per day, proportional (charged to each late delivered component)

Notes

  • Classes are not mandatory, but student absences will be recorded.
