STUDENTS 'TEACHING OBLIGATIONS AND THEIR PERFORMANCE:
1. Attendance at 75 percent of lectures
2. Completed laboratory exercises, submitted reports.
CONDITIONS FOR OBTAINING A SIGNATURE:
After completing all forms of teaching, the student receives a signature, which is a prerequisite for taking the exam.
TEACHING METHODS:
Lectures and laboratory exercises.
METHOD OF KNOWLEDGE EXAMINATION:
The final grade from the entire course consists of the grade from lab exercises and the grade from partial exams.
Checking the knowledge and readiness of students from the practical part of the lab exercises, (15), consists of an entrance exam for each exercise, 1 point, and processing the results from the exercises report for each exercise, 1 point.
During classes, students can access the knowledge test, through partial exams. The whole course has 3 exams, each partial exam consists of 10 questions that are scored with 1 point, and it is considered that he has passed the partial exam, if he answered 6 questions, 60%. Each partial exam has a min threshold as well as lab exercises, see table.
Students who have not passed the exam through the partial exams are required to write a written exam, which consists of 15 questions that are scored with 2 points, the maximum number of points is 30, the minimum is 18, 60%.
In case the student wants a higher grade, he can retake the written part of the exam. Attendance at classes is scored with a maximum of 5 points, and absence of 3 times or 25% is scored with 3 points.
