Why DET scores get stuck below 105
Most students at this level do not need more random English practice. They need to find the specific skill capping the score.
Problem 1
The score report is too broad
The DET gives you a number, but it does not tell you the real cause. A student may think the problem is vocabulary when the real issue is answer development, sentence control, timing, or weak explanation.
Problem 2
Speaking answers stop too early
Many students can answer the question, but they do not develop the idea far enough for a higher score. They speak correctly, then stop before the answer has enough detail.
Problem 3
Writing sounds simple, not controlled
At the 85–95 range, writing often has basic grammar but weak structure. The answer may be understandable without sounding organized, developed, or test-ready.
Step 1 · DET diagnostic
Find the skill blocking your 105.
The diagnostic is the entry point into DET 105 Score Repair. In 60 minutes, LU English checks your speaking, writing, grammar control, answer development, and timing under DET-style pressure.
You leave with a score-cap explanation and a clear repair plan. You can continue with LU English or use the plan on your own.
Book the diagnostic — $25 →Speaking — can you develop answers under pressure?
We check whether your answers are too short, too basic, too slow, or missing clear explanation.
Writing — does your answer sound controlled?
We look at structure, sentence control, clarity, and whether your ideas sound developed enough for the score you need.
Grammar — what breaks when the timer starts?
We identify the grammar patterns that collapse under pressure, not just the grammar you know during normal practice.
Your repair plan — what to fix first
You leave with a clear priority order, so your next study session is not a guess.
