Exam relevant topics and solution suggestions for exams 2023, 24 and 25

In the last lecture of the course today, I gave a short overview of exam-relevant topics that can be found here and went solved a few problems from previous exams. My solution suggestions can be found here: 2023, 2024, and 2025. I've also moved all shared lecture notes to the folder lecture-notes (moving it from the external cloud service it used to be on).
