Eligibility for exams
Students must attend 2/3 of the practical classes to have access to the final exam.
Calculation formula of final grade
Students may do 2 mid term written exams and will be aproved if the sum of the two exams is higher than 9.5 values.
Students may do a final written exam and will be aproved if classification is higher than 9.5 values.
Students that are aproved in the mid term exams may also do the final exam but then only the final exam classification will be considered.
