Quien quiere practicar inglés conmigo?
ok, it seems by the way you write you know more than what your status say, english level 5?. Anyway, i didn't pass through all units one by one, so i've no idea how much english you should know by now. i took the test that allow you to know your already level in english and i did skip 34 units at once with a 9 overall level. that's ,of course because i already knew some english. it looks like it's the same with you.
You're rigth, I know some english too. I joined Duolingo just 3 days ago, and I'm passing through every unit, one by one, I think it's fun, and it helps me to remember some words, and grammar, so that's the reason I didn't take the test.
