Very useful!

I took Spanish in high school and college years ago, and Duolingo has helped me improve my Spanish proficiency after not using it for so long. It works if you use the app consistently.

The only negative is I have a little trouble when Im supposed to repeat sentences. In some cases, Im told that Im saying things incorrectly even when I know theyre correct.

Id love it if Korean were one of the languages offered.
