What does fluency actually mean?
I was looking at my sister's account and I noticed she was a lot less fluent than me, even though she is way ahead of me in the activities and Level, and I am 45% fluent and she is only 40%. I considered the fact of me only doing skills when all my other skills are golden, because she does not strengthen her skills very often... But it didn't really make any sense. Thanks for the help!
