Join the club for serious Korean learners.
Every saturday at 12 PM EST, people with less than 50xp for the week will be kicked.
You should say it is a Korean Club for "insane" learners, as it is the name Duo gives for a 50xp per day method. I guess it wouldn't sound attractive though. And you also might get some actual insane people. hehe
I think the "insane" label is a mistake by Duolingo as it gives people the impression they will make progress with a lot less than that.
I'm not sure about that. I think they just want to be playful, as they usually are on the exercises. I think it is incorrect to put a time next to the commitment you choose. Even though I'm on "serious", I spend waaaay more time trying to understand the grammar, reading, listening and saying out loud the sentences than the described time. I also read some of the comments on the sentence discussions and try to help other people when I can. ...or maybe I'm just slow hehehe
