- Sixty minutes with a teacher
- A named priority, not a score
- The right next step for your DET preparation — or none
What the session covers
The exact shape depends on the student. These are the areas a teacher works through in the DET diagnostic.
The student’s goals
What they are working toward, and by when.
Current performance
A teacher observes real work rather than reading a past result.
Repeated weaknesses
The pattern that keeps limiting progress, named plainly.
Teacher observation and feedback
Spoken feedback during the session, in plain language.
A recommended next step
The right next step for improving the student’s DET performance — or that none is needed yet.
This may be useful if
- A DET score has stopped improving despite steady work
- You are preparing for the Duolingo English Test and unsure what to fix first
- A parent wants targeted support rather than general lessons
- The same mistakes keep returning after practice
- You want a professional starting point before buying DET lessons
What it is not
- A guaranteed score increase
- A full course
- A commitment to continue with us
- A generic placement quiz
- An automated app result

What students say after working with us.
“The strategies I learned changed how I respond under pressure. I became much more confident and precise — my DET responses improved immediately.”
Omar B.
“The teaching approach is truly incredible — techniques completely outside the box that make a real difference. I’m really happy to see my progress.”
Ana Luiza
“Since starting classes with LU English, I’ve been able to think in English. The most important thing isn’t grammar — it’s how to use it in real situations.”
Matías N.
Results vary by starting level, study time, deadline, and test-day performance.
Common questions
A one-time session with a teacher, specific to the Duolingo English Test. We look at how the student actually performs on DET-style work, identify the pattern holding their score back, and tell you which next step is worth taking.
The DET diagnostic gives the student a clear starting point. Continuing into lessons is a separate decision.
