Common DET Struggles

Stop struggling with
test prep

Thousands of students face the same challenges. Here's what's holding you back from your target score.

📉

Score won't improve

You practice but don't see progress because you don't know what specific mistakes you're making.

Don't know what to study first

Without a clear plan, you waste time on areas that won't impact your score the most.

📚

Hard to find good study materials

Scattered resources make it difficult to know what's actually effective for the Duolingo English Test.

📖

Don't know how to learn DET vocabulary

Generic apps miss DET-specific words and phrases that actually appear on the test.

Arno solves these problems

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!

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.
