Further information

The student confirms his/her place in the course by being present at the beginning of the lesson or in any other way agreed with the teacher, for example by returning the first learning assignment. If the student is unable to attend the start of the course due to illness, he/she can also confirm his/her place by informing the teacher in advance.

Learning assignments must be returned by the deadline. The course will not be assessed if the assignments are returned after the deadline. In this case, the student must register for the next semester's course.

Compulsory attendance at CT-lectures. The absence will be compensated by an assignment determined by teacher.

It is not allowed to use or distribute any tasks, assignments or MATERIALS in any other way than in the student's own studies. Distributing ONLY with the teacher's personal permission.

Instructions on the use of artificial intelligence during the course are given separately. Students should familiarise themselves with Metropolia's AI guidelines and follow them in their study attainments.
