Teaching method

Theoretical and theorico-practical lectures thaught in classrooms with oral communication of the teaching programme and resolution of exercises. Teaching activity supported by a webpage in Moodle@FCT platform where all the teaching materials are available (slides of lectures; solved problems; additional problems; tests).

Evaluation method

Two theoretical tests (TT1 and TT2) and two theorico-practical tests (TTP1 and TTP2).

The theoretical classification (CT) is obtained as follows:

CT = 0.50 * TT1 + 0.50 * TT2

The theorico-practical classification (CTP) is obtained as follows:

CTP = 0.50 * TTP1 + 0.50 * TTP2

The final classification (CF) is calculated as follows:

CF = 0.60 * CT + 0.40 * CTP

The student succeed if CF ≥ 9.50 (in 20). The student does not succeed if CF < 9.50 (in 20).

The students must do the Final Exam if CF < 9.50 (in 20), or no test was done by the student. 

The students can do the Final Examination if they want to improve the CF score obtained in the tests.
