The obligatory subjects for STX students are: classical studies (oldtidskundskab) (level C), religious studies (C), Danish (A), English (B), history (A), mathematics (B), physics (C), physical education (C), and social studies (C). In addition, while English is compulsory for all, each student also has to study another modern foreign language at either A or B level depending on whether it is taken continued or as beginner (the most common are German, French, Spanish and Italian). Continued language courses on B level are only available for German and French. The student is also required to study an artistic subject (e.g. music or visual arts) at level C, and two of the subjects biology (C), chemistry (C) and physical geography (C). Most of the obligatory subjects can be studied at a higher level if the student elects to do so.
