Obtenção de frequência

The frequency is achieved through:
Carrying out 2 written tests or an exam and the planned laboratory work

• Test 1 and Test 2 with a minimum score of 8.0 values.


• The Mean of Test1 and Test2 has a minimum rating greater than or equal to 9.5 values (≥9.5 values) on a scale between 0-20.


• The exam grade has a minimum grade greater than or equal to 9.5 points (≥9.5 points) on a scale between 0-20.


• Carrying out all laboratory work with a minimum rating (in each laboratory work) greater than or equal to 9.5 values (≥9.5 values) on a scale between 0-20.

Fórmula de cálculo da classificação final

The final classification is obtained as follows:
CF=0.7*T+0.3*L

where,

• T is the mean of the two tests (≥9.5 val.) or the exam grade (≥9.5 val.). Grades greater than or equal to 17 are defended in an oral exam.


• L is the average of the grades of all laboratory work (L≥9.5)
