## 📐 Presentation Rules for 12th Grade
1. **Derivations:** Diagram (Left) $\to$ Theory (Right) $\to$ Step-wise derivation $\to$ Final Boxed Formula.
2. **Organic Chemistry:** Show the **Intermediate** state if the mechanism is asked. Use curly arrows for electron flow.
3. **Math:** Mention the property used (e.g., "Using Property P4 of Integrals").
4. **Biology:** Use a **Dark HB Pencil** for diagrams. Labeling should be on one side (Right) whenever possible.

## 🧠 Mental Edge & Discipline
- **The "No-Zero" Day:** Even on bad days, solve 5 Math problems or 2 Derivations.
- **Active Recall:** After every chapter, close the book and write down the "Formula Web" from memory.
- **Exam Simulation:** Sit for 3 hours *without* phone or breaks once a week. Stamina is as important as knowledge.
