IMPORTANT: Update in seating arrangement

Written on 16.02.26 by Sanyam Agarwal

Hi all,
Due to renovation in E1 3 HS002, we can't use it for the exam tomorrow. Consequently, students seated in HS002 have now been re-allocated to E1 3 HS001, or E1 3 HS003. You all are requested to have a look at your seating arrangements again and come to the assigned room accordingly. Thank you for your cooperation.
As a reminder, please be at your assigned lecture halls latest by 8:50am, and bring both: a student ID, and an official Photo ID.

Best of luck!

No recording today

Written on 18.12.25 by Markus Bläser

There is no recording of todays lecture, since we had to swap the laptop. Sorry. Please watch last year's lecture.

Dear all,

we updated the available tutorials in the CMS. This might have erased your preferences. Please check and, if needed, re-enter your selection.

If you need an English-speaking tutorial, pick a time slot where one is available and then go to that tutorial, even if you were assigned the German-speaking one.
We kindly ask the German-speaking people assigned to an English tutorial to load-balance in return.
