There is no option in the list can make me learn English
Duolingo currently offers English courses through French, Italian, Portuguese, German, Spanish, Dutch, Turkish, Russian and Hungarian. If none of those are your native language, then I'm sorry.:( Your native language might be added eventually however. To switch to one of the currently offered courses, hover over the cog and select "Settings". Once there, you can select any of Dulingo's courses in the "Learning Language" dropbox.
