Evaluation Methodology
Final Average = PT 30% + PP 70%
PP = DP 80% + MD 20%
PT can be taken in the modalities Attendance/Exam/Special/Student Worker.
PT = Theoretical Part/ PP = Practical Part/ DP = Practical Performance/ MD = Descriptive Memory
The values of the Final Average of PP and PT must be equal to or greater than ten values.
