Coursework requirements
Godkjente regneøvinger, Approved laboratory exercises

Compulsory laboratory exercises: 8  Compulsory hand-in assignments: 5 out of 8

Completion of mandatory lab assignments are to be made at the times and in the groups that are assigned and published. Absence due to illness or for other reasons must be communicated as soon as possible to the laboratory personnel. One cannot expect that provisions for completion of the lab assignments at other times are made unless prior arrangements with the laboratory personnel have been agreed upon.

Failure to complete the assignments on time or not having them approved will result in barring from taking the exam of the course.
