I speak English but accidentally click French, how do I change the language for my course?
Start a second browser and access duolingo com. In the top right corner, set the site language to English. Then log on via "I already have an account" (avoir deja un compte). In the top right corner, go to Profile > Settings (reglages). On the far right, select language studied (langue etudiee). Now select display all language courses (afficher tous les cours de langues). The new interface displays languages to learn via flags, but you can also select your source/native language in the top right corner: I speak French (je parle francais).
