Sophie Moore
Alexia from Peru

It was a wonderful experience to practice for my Duolingo exam with Arno. Not only did it help me improve my score from 100-110 to 120-130 on Duolingo's practice test, but I also learned how to enhance my word selection in the writing and speaking sections through AI-based instructions from Arno.

I was so desperate when I found Arno. I had taken the Duolingo English Test three times already. I practiced with Arno for two weeks and I finally passed it with 135 overall score and 105 Production score! I am so grateful, thank you Arno!
