### Course requirements

70% attendance in exercises, you get exercise points from

- non-Matlab tasks (have to be done
*before exercises*)
- Matlab tasks (have to be done
*in exercises*)

### General information

Each exercise is focused mainly on topics that are covered in the lectures week before
them, so there are no exercises in the first week. Non-Matlab tasks
(old-school pen&paper tasks) have to be done before the exercise session,
and in the beginning of the exercise session you will mark which tasks you have
solved (your solution does not have to be 100% correct, as long as you have seriously
tried to solve the task). Note that marking a task as solved means that the assistant
may ask you to present your solution on the whiteboard; Matlab tasks are meant to be done
after this in class, where you can ask advice from the assistant.
**The assistant will check the Matlab tasks when you are ready and give exercise points for them.**

### Course grading

By completing the exercises beforehand and during the exercise session,
you can earn bonus points for the exam. Points attached to the successful completion of the exercises are:

Exercise points | Bonus points for the exam |

at least 40% | **1** |

at least 60% | **2** |

at least 80% | **3** |

at least 95% | **4** |
