The quality of different language courses on Duolingo differs a lot. For example, the Finnish language course is very bad, full of useless words and nonsensical phrases like "The cat is a viking". In contrast, the Swedish course (which happens to be the 2nd official language of Finland) is amazing and full of phrases immediately useful in daily life. A few modules in, Finnish Duolingo is all e.g. "My mom is a shaman" and "The cat is a viking", while Swedish is e.g. "I'd like a glass of cold water" and "Emma wants a pizza".

In addition, the multi-modality also differs a lot. Finnish and some other languages simply don't have speech exercises (where you have to read something into the microphone).

They have the speech exercises in Spanish, but they are ridiculously bad. It often says I'm correct before I get to say half the sentence. Other times, I'll need to repeat a word 10 times until it gives up and says it's fine.

So in other words, the course is programmed by a human?

Well I hope with today's AI tech the course should be highly customizable. I don't want to learn "The cat is a viking" 100 times.

Great for telling people you are doing something, that's all.

For me, the best has been to get a anki deck to get the most basic 1000 words, once finished, go find a tutor to speak 1h a week on Preply and then create a personal Anki deck with words you encounter.

That has been the easiest way to improve for me. And this is for Japanese, one of the hardest languages I tried learning.

The main tag line on the WaniKani website, "2000 Kanji. 6000 Vocabulary words. In just over a year." is very optimistic, I'm around level 12 (of 60) after that long. It might be possible to do it all in a year, but you need to put in a lot of work.

It actually has a very different learning philosophy from WaniKani so it is not really an alternative.

* shodoku teaches writing as well as reading, the point being that writing it helps you remember it.

* You learn components (radicals) and vocabulary at the same time as the associated kanji.

* The order doesn’t need to be by simplicity. This is deviates from both WaniKani and Remembering the kanji.

* You rate your self, just like anki.

I find it is actually more important to learn the kanji in the words you are learning, if a new kanji has three new components, it is not hard to simply learn these new components at the same time (and create a story / connection of them). And learning the reading of the kanji is easier if you learn words containing it. So what I do is I bookmark a couple of words each time I start a new kanji card, and during reading review, if I remember how these words are pronounced, I rate it as good.

1. Go through hiraganas a few times (however you prefer, I would write a few down on paper and try to memorise them but now I'd probably just get an Anki deck for it)

2. Once you feel generally comfortable with that, move to words (100 or so) using hiraganas only (try not to get words converted from kanji to hiraganas but actually common words that are always written in hiragana - use ChatGPT to generate a deck for you)

3. Once you feel you arw comfortable, move to the most common 1000 kanjis. There are tons of decks but I really liked the G-Anki one. Go through it once.

4. At this step, you can read and speak much more than you imagine, time to practice it. Here you would move to writing, reading or speaking (depending on personal goals and preferences). I found a tutor which spoke in a way I could understand and that I felt I could relate to (and I wanted to learn a bit of Kansai dialect, so that also helped). I did that on Preply as it is easy to see people's introduction videos and trial a few if needed.

5. As you write, read or speak with natives, every time you use a word you didn't know but you think you should (be picky, add a phrase which seems simple but don't get but don't necessarily add some extremely technical jargon you'd never use ever, at least not for now).

6. Keep going. This is a marathon, not a sprint. This stage, if you did the Anki decks daily, you could reach it in 1-2 years, depending on your inclination, how much Japanese you were previously exposed to, etc.

I am now at my 5th year, still learning with anki decks, speaking to my tutor (who became a really good friend) and adding new words. I started reading some short stories fully in Japanese, and almost played through Pokemon Scarlet completely in Japanese. I still cannot follow animes without having to stop and read the text but that's not my goal for now.

Good luck and keep it up!

I do 1-2 Duolingo lessons daily, supplemented with 15-30 minutes of real Japanese study. If I can't skip ahead after completing the first "star", I feel disappointed. I'm often able to skip two or three units in a row.

Though this is partly because I'm only using Duolingo as an easy, gamified supplement to serious study.

I was under the same impression, but later the problem disappeared. You have to give Duolingo a couple of months of learning effort first, so that Duolingo has a larger base of sentences that you should already understand.

To answer the question, it depends on which language you're learning. Japanese and Spanish probably have the most resources for English-speaking learners.
