Credits are also called ECTS-credits (European Credit Transfer and Accumulation System).

In the past, the workload of a class was expressed in weekly hours or semester hours (SWS), irrespective of whether the class was a lecture or a seminar. Today, the amount of time you spend preparing for a class is also taken into account. This means that the overall workload can be calculated which is much higher for a seminar than a lecture. The units for measuring the workload are called ECTS credits. Study achievements can be compared and transferred to another university or even to another country using ECTS credits. A Bachelor’s degree is worth 180 ECTS credits. In the calculation of the workload, 1 ECTS credit is equivalent to about 25 to 30 hours of work.
