## 💡 Quick Tips

1. **Start with Value Objects** (LeadScore.vo, Rating.vo) — They're the simplest
2. **Use the templates** — Don't write from scratch
3. **Test one file at a time** — Don't jump around
4. **Read the test scenarios** — They tell you what to test
5. **Verify the formulas** — Stats calculations are critical
