Natural Science Line 

As its name implies, Helsinki High School of Natural Sciences is a city high school that has been given a special task in teaching science . About a third of the students study in the natural sciences. The science line has a tighter screen than the high school general line.

In the Natural Sciences line, students emphasize natural sciences in their studies by choosing at least 12 courses in biology, physics, chemistry or geography in addition to the compulsory courses. In this case, the student may choose to omit eight compulsory courses in other subjects from his / her study program. However, at least half of the compulsory courses must be taken in each subject.
