would definitely recommend Arno to other students who are preparing for the DET. His platform helped me improve my reading and speaking skills, and the practice questions were very useful. I also liked that his videos explain strategies clearly and simply, which made the exam feel less stressful and easier to understand.

It's totally useless for me. I'm only using it because my student wants it. When I open the website, CPU usage rockets, like if the website was doing intensive mining.
Response from ArnoMay 2, 2026
Hey Nabil! This is the first time we've ever heard a complaint about high CPU usage because of Arno. Arno doesn't use the CPU much because the processing happens server-side. Are you sure the CPU spike is because of Arno and not another app?

Honestly, I would have given it a 2-star rating at first. There were so many bugs, and it felt like the team just didn't care. But after using it for about a month and a week, my opinion has completely changed. First of all, their feedback is incredibly fast. Whenever I found a bug, I took screenshots and explained the context clearly so the developers could easily understand. I didn't get much compensation compared to the number of bugs I reported, but honestly, looking at it another way, the quick responses and fast bug fixes are a reward in themselves. My perspective has really shifted now. There are still some bugs in the mock exam total score calculation, and the AI glitches out from time to time, but despite that, this level of rapid feedback and patching is genuinely impressive.
