Eligibility for exams
According to the general rules
Calculation formula of final grade
Final classification is obtained as follows:
1st evaluation scheme:
a) First test covering chapters 1 to 4 schedulled after the Easter break
b) Second test covering the remaining chapters schedulled for the exam date
In this scheme tha final grade will be an average of the classifications obtained in both tests as long as both grades are higher than 8. If any of the classifications is lower than 8 students must follow the 2nd evaluation scheme.
2nd evaluation scheme:
Final exam covering all the chapters
Note: The resit exam will also cover all the chapters
Classification improvement
It will be done during the resit period
Observations
For approval, the final classification must be higher than 10.
