Why is my fluency going down??
So when I first started German with Duolingo. I tested out of the first 8 lessons, and my fluency was at 6%. As I continued doing new lessons, my fluency went down to 5%. And NOW I have completed about 23 lessons and my fluency has gone down again to 4%. All of the lessons are gold (meaning I went back and increased proficiency. Which I do every single day before starting new lessons). And it's not like I'm getting a ton of questions wrong either. I've never run out of health...
What am I doing wrong?
The fluency will fluctuate from time to time, depending on how much and what material you've practiced. Usually, it will max out between 50% and 60% fluent, but users have achieved higher and lower fluency percentages. It's based on the accuracy of your solutions in learning sessions and the progress you've made in that specific course.
If you haven't already, please see this article from Duolingo's Help Center thoroughly explaining what the fluency percentage means:
