Question session - Zoom link was wrong

The Zoom link on the webpage was wrong until 13:00 today! Before that I was (alone) in another Zoom meeting and was wondering if no one needed my help. Feel free to send me an email if you have any questions, and I will try to help (we can do a Zoom meeting for instance). Next Monday evertyhing will (hopefully) be back in order.

PS: I have posted solutions to the weekly exercises for week 16 and 17.
