Students Evaluation

Assessment Language: English / Greek
The final grade of the course is formed by 70% by the grade of the theoretical part and by 30% by the grade of the laboratory part.
1. The grade of the theoretical part is formed by a written final examination.
The written final examination of the theoretical part may include:
Solving problems of application of the acquired knowledge, short answer questions, comparative evaluation of the theory elements etc.
2. The examination of the Laboratory Exercises is carried out with the continuous evaluation of the laboratory skills and the theoretical knowledge that were acquired in the course by the method of the continuous evaluation of the weekly lab exercises.
