Previous exam problems with solutions.

Lecture plan

This is the lecture plan for the autumn semester 2022. Lecture 1-14 will consist of a 3h lecture in A1-040 (Fri 14-17).
Office hours: Mon 12-14 and Fri 10-12 at my office B4-032. I have an open door policy, which means that you may come to my office at other times (no appointment needed).
Plenary sessions: Mon 16-19 (four sessions). In plenary sessions, I will solve selected problems. See the lecture plan below for details.
Exercise sessions: Mon 16-18 (weekly). In exercise sessions, you will work with problems, and teaching assistants will be available to help. See the lecture plan below for details.
