OK...here's a gripe from a fully ripened ego. I ran through duo-lingo in two days, and got 'certified', and my fluency was figured at 53 %. My French, learned on the streets of Paris, allows me to pass among the French and not be mistaken for a foreigner. I've been called on to translate and interpret workshops going both ways...
I'm now four months into this, and I'm only 56% fluent. Fifty-six! What? But that's not the worst. Many of my students have become competitive, and one of my first years is approaching forty percent!
What am I going to do, when one of my students is more fluent than I? What is the formula for increasing fluency? Do you guys have no mercy? Is there any button I can push to provide artificial intelligence, for my reputation's sake?
Yours with tongue in cheek.
