Assesssment methods and criteria:
Classification Type: Quantitativa (0-20)
Regular Season - is evaluated in the 3 frequencies that are designed to measure students knowledge (by theoretical and theoretical-practical issues/problems). The 1st frequency will have a weight of 20%, 2nd frequency will have a weight of 40% and 3rd frequency will have a weight of 40%. Students who have a final classification (weighted classification of the three frequencies) of at least 9.50 values will get approved. Appeal and Special Season - are evaluated with a test that aim to assess the theoretical and theoretical-practical knowledge. Students who have a rating in the examination of at least 9.50 values get approved. Note: Students who achieve a rating of at least 18.5 values will have a provisional classification of 18 values. However, they may submit to oral examination to qualify to obtain a final grade above 18 points.
