I'm curious...because i want to do one to...but how do i create and immersion?
Some languages have immersion. Some don't
Some people have immersion. Some don't. (Because Duolingo is doing "A/B testing")
If you have immersion, it will show near where it says "Home Activity Discussion" or "ホーム 履歴 ディスカッション"
If you want Spanish immersion, you could try making a new account. Choose "English" for your language. Choose "Spanish" as what you are learning. If you are lucky, the new account will have immersion. But it might not.
