Teaching methods and learning activities

The classes being theoretical and practical there will be periods of theoretical exposition of the concepts and techniques with solved examples, followed by periods during which the students should work out, by themselves, proposed problems and exercises. The therotical exposition will be done at the blackboard or with slide projection. The students will be given texts containing the theory as well as lists of problems and exercises to solve.

Eligibility for exams

The presence of each student, in the classes, is registered. The student cannot miss more than 25% of the previsible classes.

Calculation formula of final grade

The evaluation in this unit will be in the following way : - the student should pass a 1st test, T1, at the middle of the semester, that is compulsory for all; - if the student pass the 1st test ( with a mark equal or greater than 10 over 20), he can do a 2nd test, T2, that includes only the subjects given after the 1st test; this second test will be at the end of the semester, both tests will have the same weight ; - if the student didn't pass the 1st test ( its mark being less than 10 over 20) then he should pass a final exam, EF, that wil be at the same time as the second test ; the final exam will have all the given subjects; nevertheless any student is free to choose todo this final exam - there will be yet a second possibility for the final exam, ER, that can be done by all the students that have not yet pass and can serve also to improv the final mark. The final mark, CF, will be than obtained by : CF=(T1 mark+ T2 mark)/2 or CF=EF mark or CF=ER mark

Examinations or Special Assignments

During the semester the student will have some proposed exercises to solve by themselves and handwriten. These should be given to the teacher to be corrected and in this way the student can have a positive information about his work in this unit. The students can be also asked questions during classes.

Special assessment (TE, DA, ...)

Following the evaluation rules in this School.

Classification improvement

In the second possibility of the final exam (ER) or following the evaluation rules in this School.
