I did it !
just completed the Swedish course so happy and learned a lot cant wait to learn Spanish now and up-keep on Swedish
Congrats on making it through the Swedish tree. From here on with Duo, it is pretty much review, review, or try to get your tree all golden. And the more you practice, the more you get xp points and the level with earned xp points only go up to level 25. You can also try to find other sources to help you enjoy learning more about the Swedish language. Movies online, e-books or buy supplemental material. I bet you will enjoy Spanish learning it and hope the Swedish helps make learning it easier on you. Italian on duo has helped me going through duolingo Spanish lessons.
I think you only finished the tree. If it's like Spanish there are 25 levels and you complete the tree somewhere around level 15. I know in the Spanish course you need 30,000 xp to reach level 25. Great job tho. Good luck with Spanish.
Some people complete their trees as early as level 9. But of course, it depends on the length of the course.
I don't know about the other languages, but for High Valyrian I finished at level 9.
Congratulations! It takes a lot of hard work and dedication to finish a course!
Good luck learning Spanish!
