Arno has helped me identify the specific question types that need improvement instead of just giving an overall score. My favorite features are the detailed performance analysis, realistic mock tests, and AI feedback for speaking and writing. The platform clearly showed that I need to improve my photo description tasks and fill-in-the-blanks, which helped me focus my preparation more effectively.

Arno helped me switch from the Duolingo English Test to the TOEFL format in record time. The platform is intuitive, and the instant feedback on the Academic Discussion essays gives you exactly what you need to fix your grammar and vocabulary to reach a C1 level. It is highly effective for students under pressure.

My experience using Arno while preparing for the TOEFL has been very helpful and practical. At the beginning, I used to struggle mainly with understanding reading passages and choosing the correct answers in inference questions. However, Arno helped me break down complex sentences and understand the meaning of academic vocabulary in context, which made a big difference in my comprehension. One of the most useful aspects for me was how Arno explains mistakes instead of just correcting them. When I made an error, it would show me why my answer was wrong and how to think more logically next time. This helped me improve not only my answers but also my thinking process during the test. I also found the writing support extremely valuable. Arno helped me organize my essays better by suggesting stronger linking words, clearer structure, and more academic expressions. Over time, my writing became more confident and natural, especially in task responses that require opinion and explanation. Overall, my experience felt like having a personal tutor available anytime. It didn’t just give me answers—it taught me strategies, improved my accuracy, and helped me feel more prepared and less stressed before the exam.
