Thank you so much, Paulina!

I used Arno to prepare for the Duolingo English Test and overall, I really liked it. The platform was easy to use and the materials were helpful for understanding the test format. I especially found the exercises for reading and listening useful. However, I wish there were more exercises for speaking and writing, especially for tasks like describing pictures, because I think that would help improve those skills even more. The feedback was helpful, but more detailed tips on how to improve would make it even better. Overall, Arno made me feel more confident for the test, and I would recommend it to anyone preparing for Duolingo.

Me gusta la retroalimentación que da la inteligencia artificial. Además, los planes de estudio personalizados con base a los test de prueba que vas realizando. También, me encanta tener muchos ejemplos de las preguntas de DET disponibles para estudiar.
