Learning methods and activities

Lectures, tutorials and laboratory exercises.

There are five mandatory laboratory exercises. Lab journals must be approved for all exercises. One formal lab report must be written and approved to be allowed to take the exam. The lecturer or lab tutor will assign the lab exercise at the end of the course.
