The worksheet, the result and what still needs reviewing
See two self-created worksheets, reference answers and an actual grading run: what the system read, how it marked each response, and why explanations still need review.
How were these examples produced?
We created two worksheets containing 12 questions with a mixture of correct and deliberately incorrect typed answers. Each sheet was graded once through the normal grading flow in the development environment using a P3 profile. No real student data or photos were used. Reference answers follow arithmetic and elementary English rules; this is not an independent teacher evaluation.
This is not an overall accuracy benchmark. It does not cover handwriting, Chinese essays, blurred photos or every year group. Development model settings may also differ from the live service.

Question 2
計算結果為 126。
Question 5
你的數字是對的，但小數點的位置跑掉了！$3.75 \times 10$ 應該是把小數點向右移一位，變成 $37.50$。記住：乘以 10 只是移動小數點，不是把數字變大十倍哦 ✨
Question 6
你可能不小心算成面積了（$8 \times 5 = 40$）。周長是繞圖形一圈的長度，公式是 $(長+寬) \times 2$。試試看 $(8+5) \times 2$，你會發現答案是 26 cm 💪

Question 2
You used the present tense, but 'Yesterday' tells us the action happened in the past. Remember to change the verb to its past form when you see time words like yesterday. Try adding '-ed' to 'play' next time! ✨
Question 4
Almost there! You spelled 'because' as 'becuase'. Notice how the 'e' comes before the 'a' in the middle part of the word. Let's practice writing b-e-c-a-u-s-e a few times to remember the order 💪
Question 6
Great effort! Look at the subject 'Tom and I'. Since this includes two people, it is plural, just like 'they'. When the subject is plural, we use 'are' instead of 'is'. Try saying 'We are friends' to help you remember! 🌟
How should I interpret or repeat these examples?
One run of 12 questions cannot establish performance on all homework, examination marking or learning outcomes. Models, questions, image clarity and service settings can change the output. Review it against your teacher’s answers and marking guidance.
Download the original sheets and reference data, select P3 and maths or English in the app, then compare a fresh run question by question. New results may differ. The JSON files provide machine-readable records without student identifiers.
