Development of the examination
LEARNING EVALUATION METHODS
Written test to be passed to stand the oral examination
LEARNING EVALUATION CRITERIA
Written test: to evaluate students' ability in applying theory and their knowlegde of parameters' unit and magnitude. Oral exam: to evaluate students' theoretical knowledge.
LEARNING MEASUREMENT CRITERIA
Written test and oral exam are evaluated in thirtieths.
FINAL MARK ALLOCATION CRITERIA
The exam is passed if both written test and oral exam are sufficient. Errors in the written test, if any, are discussed during the oral exam; therefore the oral exam is more important than the written test for the final mark. Full marks are assigned in case of correct written text and correct and brilliant oral exam with a proper technical language.
