So I'm learning Vietnamese while some of my other friends are learning other languages. Whenever they complete a lesson it tells them their fluency in their language. It also tells them their fluency on their homepage. I was wondering how I could find out my fluency percentage?
The fluency feature is only available for a few languages. Vietnamese must not be one of those, but trust me, you're not missing out on much.
Unfortunately, the fluency percentage is very inaccurate and it would be best not to even waste time looking for it.
You can find more about the fluency percentage here.
You see, it is almost impossible for a computer to distinguish your fluency - in the unit of a percentage - with just the information given while you take lessons. If you go to Vietnam, or start talking a lot with Vietnamese friends, that won't improve your fluency, because Duolingo will never know about it. It is best to just ignore the fluency percentage and keep having fun and learning. =)
