The number of years of instruction at a Gymnasium differs between the states. It varies between six and seven years in Berlin and Brandenburg (primary school is six years in both as opposed to four years in the rest of Germany) and eight in Bavaria, Hesse and Baden-Württemberg among others. While in Saxony and Thuringia students have never been taught more than eight years in Gymnasium (by default), nearly all states now conduct the Abitur examinations, which complete the Gymnasium education, after 13 years of primary school and Gymnasium combined.
