Can I change my course language?

No, once a course is created its language can't be changed. This is a deliberate design decision.

Why:

The curriculum, level test, lessons, visuals and all content are generated in the language you chose when opening the course. Changing the language later would require the whole curriculum to be rewritten.

In practice:

• If you opened your course in English, all lessons will be in English.
• You can create a new course for the same subject in a different language.
• Example: you can have one English and one Turkish course for "Python basics", as two separate courses.

Interface language ≠ course language:

• From Settings you can change the interface language any time (menus, buttons, etc.).
• The course content stays in its original language.

Will lessons change if I switch the dashboard language?

No, the dashboard (sidebar, menus) changes with the interface language; lessons stay locked to the course's own language. For details on the eight interface languages, see What is Vunolin?.
