There are no formal requirements about solving the exercise problems.

If you want a small bonus for the exam,
you can return your answers in written form (on paper or by email).
This is the only way to get a bonus.
You have to return your answers one day before the exercise session
(that is, on Monday).
Doing 75% of the exercises gives the maximum bonus.
Read the
instructions (pdf)
carefully.

The exercise sessions are meant for
discussing and going through the exercise problems.
Attendance is recommended but not required.

We will use
lecture notes (pdf)
written by Valtteri Niemi in 2013,
sold at Delta's office.
I wrote a short list of
corrections (pdf, updated 18.10.2016)
and two appendices.

Appendix A:
Basics of finite fields (pdf).
The material here might be familiar from other courses.
