Why test scores stop moving
Most students already know enough English. The score isn't moving because they're practicing the wrong thing.
Problem 1
The scores don't show the real cause
The DET gives you scores, but it doesn't show the real cause behind them. It won't tell you whether your writing structure, speaking fluency, reading speed, or idea development is the real issue. Without that, every practice session is a guess.
Problem 2
Their writing structure doesn't match English logic
Many students bring writing habits from their first language into English. In some languages, the main point often comes at the end. In English test writing, the reader expects the point first — and unclear structure can pull the score down.
Problem 3
They finish ideas too early under pressure
Test scoring rewards development, not just correctness. Students often stop a sentence one step before the idea is complete. The fix is specific — and fast — once it's identified.
The diagnostic session
60 minutes. A ranked fix list.
In one session, we work through your speaking, writing, reading, and listening — and identify exactly where you are losing points. You leave with a specific diagnosis and a ranked list of what to fix first.
Most students have been practicing the wrong thing. The diagnostic stops that immediately.
Book the diagnostic — $25 →Speaking — fluency and structure under time pressure
We identify whether it's vocabulary access, sentence structure, or response speed that's costing you.
Writing — does your structure match English logic?
We look at whether you're leading with your main idea or burying it — one of the biggest structural issues for non-native writers.
Reading & listening — speed vs. comprehension
We pinpoint whether you're slow, guessing, or losing points to inference gaps.
Your ranked fix list — what to work on first
You leave with a clear priority order. No more guessing what to practice.
