### Exam

The oral exam takes 30 minutes, you can choose a topic to start with.

Here you can find a list of guiding questions for the exam as well as some examples of suitable topics to start with.

The content of the exam is based on the lecture and my handwritten notes - the detailed latex notes are thought to be additional information.

In particular, sections and paragraphs with a star (*) have not been discussed in class (and are not required in the exam!).
