✍️ 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.
