What exactly does the "Practice" button do?
It seems obvious that it recaps all words learned in the bracket it's next to, but it has also given me words I haven't learned yet?
Don't get me wrong it's not terrible as it's only extra content, but it wasn't made totally clear what it does exactly. I hope the duolingo crew has a tutorial planned for the launch.
It recaps all of the lessons; I don't know if it does a combination (many lessons in one practice) or just recaps one lesson. It is very useful.. I will sometimes take about 20 practices in between lessons just to get everything re-memorized before learning more.
