Duolingo or Memrise?
I have an profile for Memrise and Duolingo . I am amzing at memrise but duolingo I am not so good at but I want more words
Why not both? I use both: Duolingo to understand the structures, and Memrise to learn words.
A lot of Duolingo courses have corresponding courses on Memrise. You might find it helpful to study the words of a section first on Memrise, and then study that section here on Duolingo, where you learn how to use them.
I use Duolingo for grammar and Memrise for verbs, they complement each other perfectly :)
They both fill different spots in the language learning hobby, they compliment each other quite well. I use both.
