If you don't have access to our group in Bilda ("DM2571 fmed12"), you might not be registered for the course. Please make sure you register by visiting your local student advisor. I can't register students for courses - not even the courses I teach and you need to be registered in order to pass the course.
If you are registered, you should have access to Bilda, but some students apparently don't. If so, please send me a mail and I will make sure that you get access to our group in Bilda (pargman-at-kth-dot-se).
