Final exam
Details
Oral examination - gradedThe students explain the application-related problems using simple examples, they explain and describe how they relate them to practical applications and which conditions must be observed. The students prove that they can relate these concepts independently to real value problems.
Minimum standard
The students need to illustrate simple relationships. The description is supported by the examiner.Exam Type
