• Exercises for the x-th lecture needs to be completed and solution electronically delivered within 14 days - with deadline shown at the corresponding item "Exercises x" from "Homework Vaults" section in the Information System of MU.
• Special points will be awarded
• to four first deliveries of solutions;
• for solutions in pdf format;
• for very interesting or original solutions;
• for discovering errors in the lecture or in the formulation of exercises.
• In the case of "cheating", that is in the case of delivering solutions produced by other students, the final grade for the course will be F.

## Exams - procedure and conditions

Exams are oral. Each student is given 5 questions and will have time for preparation of answers/solutions (about 1 hour). The number of questions student has to answer will depend on the number of points the student received for solution of home exercises using the following rules related to the number MAX - the maximum number of points achieved in homework exercises (ie. the number of points of the best student, including bonus points).
1. If the received number of points is > 0.8 MAX.
The first 5 students will automatically receive the grade A. The rest of students in this category will receive, on their request, the grade B but can go to the oral exam to answer 1 question (out of 5) in order to get A.
2. If the received number of points is > 0.65 MAX
The student needs to answer at the oral exam only 2 out of 5 questions.
3. If the received number of points is > 0.5 MAX
The student needs to answer at the oral exam only 3 out of 5 questions.
4. If the received number of points is > 0.35 MAX
The student needs to answer at the oral exam only 4 out of 5 questions.
Each set of 5 questions will contain, with large probability, one example discussed at exercises/tutorials sessions.

## Conditions for receiving credit ("zapocet")

To get > 0.35 MAX of points from home exercises or to answer 2 out of 5 questions at the oral exam.

## How to deliver solutions to home exercises

1. Number of exercise set - number from 1 to 10
2. Name - given names + family name
3. UCO (University identification number)
