In 1903, the lines of study were changed to mathematical-scientific, modern-lingual, and classical-lingual, and the name of the schools was officially changed to "gymnasium". From 1958 there were two lines of study, mathematical-scientific and linguistic, and after first year, the students had to choose between different branches (e.g. modern languages or classical languages). This system was however changed in 1988, where the students in their second year were able to choose more freely between a variety of subjects (a student could for instance have both a language and a scientific subject at the highest level, even if he had originally chosen the mathematical line of study).
