Teaching method

Lectures and problem-solving sessions (4h00). 

Evaluation method

There are two mid-term tests. The final mark is the arithmetic mean of the non-rounded grades of the tests.

To be approved in final exam, the student must have a minimum grade of 9.5 in it.  

More detailed rules are available in the portuguese version.
