Arno is exactly what I was looking for; it's been a total game changer in my DET preparation. All the available questions, mock tests and the invaluable feedback it provides really prepared me to do my best on the test. I highly recommend it!!!
Alexia from Peru
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
Before using Arno, I was stuck at 120-130 in my DET practice, struggling with writing. Arno’s AI feedback was a game changer, helping me refine my skills. Thanks to Arno, I achieved a 140 on my actual DET. Highly recommend!

Sincerely thanks for your dedicated efforts for such an incredibly useful website and the instant feedback feature that helped me prepare for the DET very effectively in the limited time. Purchasing credits for instant feedback is a smart move and also a worthy investment.

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.
Basira from Afghanistan
I was hitting a wall with my speaking and production scores —then came Arno's website. In just 1.5 weeks of practice, I skyrocketed to a 130 in both scores. Huge thanks to Arno for making such an amazing, game-changing platform !!!

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!
