The education is developed continously. As a student you go to class, do the practicals and do the exams. You participate in subjects which are taught for years, but also subjects which only exist for 1 year. It is important to think you are prepared enough for the exams, that the subject is related to the content, that the teacher helped you enough, and that the organisations of the subject ois done well. This not always the case. Luckily, the organsation of education is open to suggestion and U.P. tries to help.
