Teaching method
Theoretical-pratical classes and practical/laboratory classes.
Encouragement to study independently through 10 Quizzes throughout the semester.
Evaluation method
Approval in the Curricular Unit is obtained with a grade equal to or greater than 9.5 Values resulting from a theoretical assessment component (80%), and a practical assessment component (3 reports- 20%). The theoretical assessment component that can be obtained by 2 tests (with weights of 30% each) + 5 Quizzes (20%) or by an appeal exam (80%). Access to the appeal exam is conditioned to students with a positive grade (>=47.5%) in 4 quizzes. The 2nd test has a minimum score of 9.0. The theoretical assessment component must be equal to or greater than 9.5 points.
Update on 05/10/2024
According to what was indicated in TPs classes at the beginning of the semester, students with a number of attendances in TPs classes of no less than 2/3 of the total number of TP classes will also have access to the appeal exam.
