## ✍️ The "Senior Sibling" Viva Hack
- **Know Your Sources:** Don't just copy. The External Examiner will ask "Where did you get this data?".
- **Handwritten vs Printed:** Most schools allow printed for 12th, but check with your teacher. A well-organized spiral binding is standard.
- **The "Safety" Question:** In Chemistry/Biology, be ready to explain the safety precautions you took.

**Command Integration:** Use `/ia-plan` to get a week-by-week timeline for completing your projects before the January Practical exams.
