Exercises are a very important part of this course. Attendance is not compulsory, but highly recommended. You do get points by attending the exercises and by doing your homework assignments.
There are several exercise groups. Please attend one of them.
If none of the exercise group times is suitable for you, but you would still like to get exercise points, you may contact the course head assistant (matias.heikkila(a)aalto.fi). Note that you need a super good reason for getting points without attendance!
