Arno helped me quickly improve my Duolingo English Test score, which was essential for my dream of becoming a master's degree student in the US. Also, Arno is one of the most useful and impressive AI app implementations I've ever encountered.

Erik from Paraguay

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!
