Lectures and exercises are planned to be given on campus.

If I (=David) cannot give the lecture on campus, I'll contact you via Canvas. Then, please use the zoom link lecture: https://chalmers.zoom.us/j/62768297711 pwd: 31415.
If Malin cannot give the exercises on campus, she will contact you via Canvas. Then, please use the zoom link exercise: https://gu-se.zoom.us/j/67019248484.

Piazza Discussion Forum:
We will be using Piazza for class discussion.
The system is highly catered to getting you help fast and efficiently from classmates, the TA, and myself. Rather than emailing questions to the teaching staff, I encourage you to post your questions on Piazza.

In order to encourage your active participation, a student will earn 1 bonus point at the exam if she/he, at least, posts one question and answers two questions. The questions/answers must be relevant to the course.

Students can also ask questions anonymously (such questions cannot be counted for a bonus point). 

Find our class signup link at:
Youtube introduction here: link

If you have any problems or feedback for the developers, email team@piazza.com.
If one of you wants to initiate and organise a discord discussion for a group of students, please fee free to do so!!
