Warunki zaliczenia

1. Checking the level of preparation of students and their activity during the classes.
2. Two colloquia with tasks of varying difficulty which allow to assess whether students have reached a minimum level of learning outcomes.
3. The exam in the form of a multiple-choice test, consisting of several dozen statements that require the verification on the basis of the acquired knowledge. The verification of statements is connected with the use of the theory or making simple calculations. The possible answers are Yes or No. The student may receive +1,-1 or 0 points for each statement.
To pass the class it is necessary to get passing scores in two colloquia. To take the exam it is necessary to pass the class. In order to pass the course it is necessary to get passing score in the exam. The final course grade is based on graded components: the class grade – 50% and the exam grade – 50%.
