► Attendance:

-For students in 1st registration:

Number of absences defined by UP regulation.

- For students with two or more registrations:

For these students there is no criterion of attendance, ie, there is no marking of faults.

► Distributed Assessment (AD) will consist of 1 test.

-The test will be quoted in the scale from 0 to 20 values, and this is the classification to be attributed to each student.

►Students enrolling for the 1st time:

To attain admission to final exams students must:

► For other students:

Students that attained the conditions of admission to final exams in the previous academic year:

EITHER they keep previous distributed evaluation grade, where the two best marks (out of three) obtained last year are considered. For these students there is no criterion of attendance, they do not need to enroll in a class.

OR they can, irreversibly, choose to take again the distributed evaluation, being the previous distributed evaluation grade canceled. They can just attend the test.

Students that did not attained the conditions of admission to final exams in the previous academic year:

EITHER take the distributed evaluation like 1st time students

OR attend only "exame de recurso", performing this exam for 20 marks.

► Regardless of the classification obtained in the distributed evaluation, all students may attend the final exam.

EXPLANATION OF DISTRIBUTED EVALUATION:

► Distributed evaluation will consist of one test.

► The duration of the test is 50 minutes, involving 7 multiple choice questions and one “classic” exercise.

If the mark obtained in the exam (EX) is lower than 8.0 (minimum to be approved in the curricular unit), the final classification (CF) will be that mark. Otherwise, the final classification is given by

CF = Max (0,4*AD + 0,6*EX ; EX)

where

CF - Final Mark (0 to 20 points)

EX - Final Exam (0 to 20 points)

AD - Classification of the test of Distributed Evaluation (0 to 20 points).

n.a.

n.a.

-Students who during the current school year are under special status (TE) are exempted from attendance. As mentioned above, they may obtain approval by AD or final examination.

Through the 2nd round Final Exam.

Final Mark will be evaluate as follows:

CF = max (CFN, 0.4 * AD + 0.6 * R, R) where

CFN is the 1st. round final grade (from 0 to 20 points), AD is the Distributed Evaluation grade (from 0 to 20 points) and R is the 2nd. round Final Exam ("Exame de Época de Recurso") grade (from 0 to 20 points).

-Any attempted FRAUD during the distributed evaluation process leads to loss of frequency and not admission to examination.

-Weekly attendance to students is accomplished through a direct negociation between the student and the professor.
