# 🧠 OLYMPIAD GOLDEN RULE
Don't ask:
**"Do I know this question?"**
Ask:
**"Can I understand the problem and find the rule?"**
Olympiad questions often test application rather than simple memorisation.
---
# 👨👩👧 PARENT TIP
After the test, don't focus only on the score.
Ask your child:
1. Which question was easiest?
2. Which question was hardest?
3. Why did you get that question wrong?
4. What concept should you revise?
5. Can you solve it again without seeing the answer?
This turns a simple test into a learning exercise.
