The way of giving the component module grades and the final grade

The type of classes The way of giving the final grade
Lecture A credit for the lecture is based on the result of the written or oral exam. There is a possibility of exemption from the exam based on a credit for the exercises.
Class A credit for the exercises is based on the results of tests and oral answers.
The final grade The final grade is the credit for the exam and the credit of the exercises (the arithmetic mean).
