Each session is organized as follows. TAs first give a summary of the relevant course content and introduce the exercises. TAs then remain in the room to assist students in solving the exercises. They finally explain the solution shortly before the end of the session.

Within one week, both tutorial sessions cover the same materials. Students are split into two groups according to their last name: Tuesday for A-K and Thursday for L-Z.

Slides and exercises are accessible only within the ETH network (wifi or VPN).

The Exercises are published on GitHub.
