The studies are measured in points, where one point is approximately equivalent to full time study for one week. One year of full-time studies equals 40 points. Then you take the next 5-point course. Part-time courses are studied over several periods. The Department of Technology, the Department of Natural Sciences have their own system with two courses studied at the same time over two periods.
All courses have a code.
This code must always be indicated on the Application Form together with the period in which the course is given. Most courses require prerequisites. If you do not meet with the prerequisites you cannot be admitted to the course.
