Location and time

More detailed agenda can be found in Moodle. Lectures will be held according to the timetable in Pakki/lukkarikone.

Exam schedules

Exam day is set during the course together with the students.

Assessment methods and criteria

Grading is based on completing group work (10%), laboratory work / excursion report (15%) and exam (75%).
Home assignments earn extra points.
Exams is a compulsory part of the course.
Group work (compulsory part of the course): Different pulping methods
Activity during the course increases the grade in borderline cases.
