# Personal Question Bank — The 12th Grade Repository

To reach 495+, you need a repository of "High-Probability" questions. Don't just solve them; categorize them so you can attack your weaknesses systematically.

## 🏷️ The "Senior Sibling" Tagging System

Every question in your bank MUST have these tags:

- **[UNIT]:** e.g., "Calculus" or "Organic Mechanisms".
- **[WEIGHT]:** 1M (MCQ), 2M (SA-I), 3M (SA-II), 5M (LA), 4M (Case Study).
- **[FOCUS]:** Board-Only | JEE/NEET | Both.
- **[MISTAKE-DNA]:** Conceptual | Calculation | Procedural. (Update after first attempt).
- **[SOURCE]:** NCERT, Exemplar, RD Sharma, SL Arora, MS Chauhan.

## 🚀 Integration with Commands

Use your personal bank to drive these commands:

1.  **`/practice [Subject] [Unit]`**: Request a specific set from your weak list.
2.  **`/mark-my-answer [QuestionID]`**: Submit your attempt for evaluation against the "Value Points".
3.  **`/graph-path [Unit]`**: See how these questions link to other chapters.

## 💡 Pro-Tip: The "L-M-H" Method
- **L (Level 1):** Direct NCERT exercises.
- **M (Level 2):** Board PYQs from last 10 years.
- **H (Level 3):** Exemplar and HOTS questions (The 495+ gap fillers).

*Your bank should be 40% L, 40% M, and 20% H.*
