Read this: Germany has a comprehensive school known as the Gesamtschule. While some German schools such as the Gymnasium and the Realschule have rather strict entrance requirements, the Gesamtschule does not have such requirements. They offer college preparatory classes for the students who are doing well, general education classes for average students, and remedial courses for those who aren't doing that well. In most cases students attending a Gesamtschule may graduate with the Hauptschulabschluss, the Realschulabschluss or the Abitur depending on how well they did in school.
