The first rule
A low score tells you what happened. Your mistakes help you discover why it happened.
Day 1 opens with three students who all got a disappointing Reading result. One blames vocabulary, one blames tricky questions. The third notices they pick answers that sound right without checking that they answer the exact question. The third student is the one who can improve, because they have found a cause. Every day of the challenge trains that habit on a different part of the test.
The case log
Fifteen days in three stages. Open a day to read its mission.
Find the cause · Days 1 to 3
01The OET Performance Detective3 recordings
Stop guessing what is wrong with your OET performance. Identify the real reasons behind your mistakes and build a personal plan to improve.
02Your Error DNA2 recordings
Find the patterns behind your mistakes, the habits that keep costing you marks, and correct the cause rather than the answer.
03The Psychology of OET Performance
Manage uncertainty, stop panic spreading across a task, stop second-guessing, and decide well under pressure.
Investigate each sub-test · Days 4 to 10
04Reading Under Investigation
Identify exactly what a question asks, find the evidence, reject attractive wrong options, and see the habits that cost you marks.
05Listening Under Investigation17 recordings
Listen strategically, recognise paraphrasing, follow changes in information, and separate key details from distractions.
06Writing Under Investigation
Stop seeing your Writing score as one number. Investigate the individual decisions that create it.

Two ways to study each day
The content is the same. Use the lesson page, the PDF, or both.

| Listening | The recording plays first; the script appears after you answer | Scripts printed separately |
| Your work | Saved as you type, on your devices | Write on the printed pages |
| Progress | Kept, so Days 14 and 15 compare with Day 1 | Keep your pages for Day 14 |
| Best for | Your phone and instant feedback | Printing, writing by hand, studying offline |
