Build your skills in live classes, meet people working toward the same goal, and choose how much personal support you need.

Join just 3–6 students who share your goal. Take part in the conversation, share ideas, and get to know people from different countries as you learn together over four weeks.
Choose a tier with one-on-one tutoring. Your tutor plans each session around your weaknesses and the areas where you can gain the most points.
Every tier includes Arno’s paid plan, so you can keep practicing between live classes. You get lessons with an expert and Arno for practice on your own schedule.
Arno is a Platinum Tier (highest-tier) member of the Duolingo Global Partner Network. Over 350,000 students worldwide have trusted Arno to help them get ready for the Duolingo English Test.
The course plan
Every class teaches techniques for specific Duolingo English Test tasks, then gives you time to practice them with your tutor and your group.

As the course goes on, you track every task as green, amber or red. You can see which skills are getting stronger and which need more attention, so you can focus on those in the next classes and get more from every session.
It’s hard to hear your own mistakes. In every class, your tutor listens to your speaking, reads your writing and tells you exactly what to fix.
You hear how others answer the same question, and they hear you. You’ll pick up ideas and phrases you wouldn’t think of on your own.

My approach is all about understanding the test, learning effective strategies, and practicing with purpose. We’ll break down each task step by step, focus on what really matters, and use practical exercises and feedback to track your progress.
My goal is to help you feel confident, prepared, and ready to achieve your target score!
