I use Duolingo every day for Spanish. It works! Several others I know are also using it for Japanese and other languages. I’m on a 1355+ day streak!
I pay the annual fee to avoid the ads and it’s worth it.
I have started doing the reverse courses in Duolingo, like Polish to English. You get a lot of new words that way.
Thanks, and good job.
I’m at a 1050 day streak, in the German course. At first there seems to be no direction or reasoning, and explanations are rare. However, as you learn it starts to make sense.
