Why Choose IELTS Ahead for DET?
🎯 Assessment-Based Strategy
Duolingo is an adaptive test, but it still requires human-quality English to score high. I use my 12 years of experience as a professional examiner to show you exactly what high-scoring responses look like and how to produce them under time pressure.
Learn About Our Method →📚 Live Teacher, No Bots
Most DET courses are just automated apps. At IELTS Ahead, you learn from Teacher Leda directly. We provide the one thing apps cannot: real, personalized feedback on your Speaking and Writing to fix errors that algorithms punish.

No two students are the same. I adapt every class to your specific goals and challenges. Being fluent in Spanish and Portuguese also gives me a deeper insight into common learning hurdles for Romance language speakers taking the Duolingo English Test.

Q: Why choose a live teacher for Duolingo?
A: Apps can’t explain why you made a mistake. Teacher Leda provides the human insight and strategy that automated platforms lack, specifically for Speaking and Writing.
Q: Is this different from the free app?
A: Completely. The app is for general practice. Our classes are intensive test preparation designed to maximize your score on exam day.
Q: My score is stuck at 105. Can you help?
