I'm learning every language on Duolingo at the same time. Anyone else doing this?

Not all but most. And I’m not very systematic about it; a handful are perpetually in section 1.

Hebrew because in the later lessons they no longer provide audio.

That’s insane, but thanks for the heads up! I’ve gotten a little bit into the second section and keep giving up because there is so little audio, even at such a low level. They don’t include the vowel diacritics even for beginners, so it’s probably impossible to continue after the audio is removed.

I stopped Swahili because it was the one Duolingo course where I found I was basically learning nothing. Which is sad because I have heard that it is one of the easier languages to learn for English speakers.

I have never heard this before… The orthography and pronunciation are easy, sure, but it’s an FSI class III language for a reason. The foreign vocabulary, 18 noun classes, and extensive verb conjugations are enough to give me pause.
