The material for KTH course ID2203 is made available here online for anyone to learn from.
Students that are taking the course at KTH should primarily go to the KTH Social course page for news and information about the course. There it is possible to ask questions and interact with the teachers and other students.
The course is using the Canvas platform for providing contents for both KTH students and for everyone else. Without logging in, anyone can watch video lectures and see the slides. If you also sign up as a user at Canvas you will be able to take the ungraded quizzes. KTH students will get an invitation to be enrolled in the course, which is needed in order to take the graded quizzes.
