Studies that include this course
Completion option 1
The course can be passed with grade 1, without taking the exam, by actively participating to the contact teaching (lectures, exercises) and completing the mandatory project work. For grades higher than 1, also the exam or two mid-term exams (välikokeet) must be completed. In general, the exam and the project work should be completed during the same academic year. More details at the course Moodle-site.
Completion of all options is required.
