The Real Problem

Why Most Students Get Stuck at 110?

Scoring a 110 is manageable. Breaking past it to 130+ is where most candidates struggle - not because they're not capable, but because they're practicing the wrong way. Here's what holds them back, and how we fix it.

No Idea What Score They'll Get

Students practice for weeks but have zero sense of their actual adaptive level - so they walk into the exam completely unprepared for the algorithm's difficulty adjustments.

Using Non-adaptive Material

Most free resources don't match the real Duolingo format. Students practice a static exam, then get surprised by the adaptive question style and interactive elements on test day.

Practicing Without Any Feedback

They record a speaking response or write an answer and have no idea if it was good, average, or weak. Without feedback, the same mistakes repeat every single time.

We solve all three - here's how
Our Solution

Instant Score Prediction


The Tech: Our AI evaluates your responses against the official DET rubric: Task Relevance, Fluency, Grammatical Accuracy, and Lexical Sophistication.

Our Solution

100% Adaptive Test Engine


The Tech: We built our content around real Duolingo question types: Read & Complete, Interactive Listening, and Write About the Photo.


The Benefit: No surprises. When you see a task on test day, you'll have already practiced a similar scenario on Prep27.
