I finally managed to figure out how to do the fluency check, and I wanted to share my results. My estimated level is B2 (Upper-Intermediate), and I was told that I’m approaching C1, not stuck in B2, which was really encouraging. I also received detailed feedback on my strengths and key limitations, especially what I need to improve to reach the next level. According to the feedback, if I stay consistent, I can realistically reach C1 within 3–6 months, so that’s my goal. I’ve tried speaking with other AI tools before, but this experience was much more helpful and insightful.
