Assessment methods and criteria
|
Oral examination, Written examination, Didactic test
The condition for participation in the exam is to obtain the credit. This condition is for full-time form of study. The credit confirms that the student participated in the required range and that he / she met the requirements that are conditional on the credit granting. The conditions for granting the credit are determined by the teacher in the first week of the lecture period of the semester. The exam for the full-time form of study is determined in accordance with the UPa Study and Examination Regulations.
