i am in french level 25, i finished it then what is there a diploma or something??
I don't think there is a diploma, but you do get the satisfaction of learning a language and testing it out. That to me, is amazing and a reward. Also, you do get lingots from learning languages on Duolingo. They can be used to purchase skills at the shop, but you already knew this ;) You can brush up on what you learned or give other websites a try. Have fun learning!
