Conditions for acceptance of the semester

Maximum of 25 % absence allowed

Mid-term exams

During the semester the student will have to write two tests on the 6th and 13th week, Based on the results those students who achieved grade 4 or 5 can keep the obtained grade as an exam grade. In order to be eligible for the exam the students have to achieve a satisfacatory grade.

Making up for missed classes

Missed practices can be made up during make-up opportunities provided by the department. During each make-up lab, only one missed practice can be executed.

Exam topics/questions

The condition of admission to the exam is the successful completion of the practices carried out in parallel to the theory.
