How to convert Duolingo levels to Language school levels?
And what level would, let's say, a well practiced and very well immersioned level 25 be in "real life"? If we try to convert it to one of those "school levels", as A1-A2/B1-B2/C1-C2, what would the maximum reachable here be?
Realistically, if you do Duolingo and nothing else, then you'll reach level A2 once you have an all-gold tree, although you'll not be far from B1 on the reading skill alone. The more immersion work you do, the higher you'll be. I suppose you could get to B2 in reading strictly through Immersion, but you should really plan to graduate to reading novels before that point.
You'll be very well-prepared to take advantage of an overseas immersion opportunity, though. Someone who finishes Duolingo and then spends a summer abroad could be a strong B2 by the time they were done--assuming they worked at it--in all but the writing skill. Note that B2 is the threshold of fluency.
I think going to the country where they natively speak the language is quite of an important step during the learning process. I actually did that before even starting with vocabulary or grammar, and it's impressive how much you learn in only a bit of time!
I'd say B1 in reading or perhaps B2 if one were very well "immersioned" indeed.
Nice term, "immersioned" :D
I'd say A2 in writing, listening, and speaking.
Sites like Lang-8 can help with writing.
Verbling communities can help with speaking.
Radio and television can help with listening.
Dedicated practice partners can help with writing, listening, and speaking.
B2 is pretty impressive. I know native English speakers that can barely communicate at C1 and many who can't communicate at C2.
Thanks for the recommendations, I would like to really use as many sources as possible to make the learning process much more complete than Duolingo alone is providing. The podcast Français Facile is helping quite a lot with listening!
