The purpose of all exercises is the growth of the student and completing the study module's goals. Vocational competence can be demonstrated in many ways, written tasks being just one way. Instead of focusing on the writing task's required length, it's better to focus on the task's goals; how can you demonstrate your vocational skill within the assignment's requirements.

The workload is also affected by the study module's contents, used study materials and language.
