# Spaced Repetition — The Memory Lock (Grade 12)

12th Grade subjects are **Volatile**. If you study *Electrostatics* in April and don't touch it until December, you will lose 70% of the depth. Spaced repetition ensures 90%+ retention with minimal effort.

## ⏱️ The Review Cycle
- **Day 0:** Deep Study (NCERT + Examples).
- **Day 1:** 10-min Scan (Active Recall of formulas/headings).
- **Day 3:** 15-min Practice (Solve 2 PYQs from memory).
- **Day 7:** 20-min Audit (Check keywords using `/ncertify`).
- **Day 14:** Integration (Link with a related chapter, e.g., link *Capacitors* with *Dielectrics*).
- **Day 30:** Mastery Check (If 90%+ recall, move to "Maintenance" mode).

## 📂 What to Space-Repeat (12th Grade Focus)

### 📐 Mathematics
- **Volatile Items:** Vector Shortest Distance formula, Inverse Trig identities, $P_4$ property of Integrals, Bayes' Theorem logic.
- **Method:** Write the formulas on a blank sheet every 3 days.

### 🧪 Chemistry (The Most Volatile)
- **Volatile Items:** Named Reactions (Aldol, Cannizzaro, etc.), Coordination IUPAC rules, Lanthanoid contraction trends, Nernst Equation signs.
- **Method:** Flashcards for reagents. Draw the "Organic Reaction Map" from memory.

### 🔭 Physics
- **Volatile Items:** Lens Maker's Formula, Gauss Law applications, LCR Resonance conditions, Bohr's energy levels.
- **Method:** Draw the "Ray Diagrams" or "Circuit Phasors" from memory.

### 🧬 Biology
- **Volatile Items:** Scientific names (e.g., *Saccharomyces cerevisiae*), Lac Operon steps, Biotechnology enzyme names, Ecology population formulas.
- **Method:** Labeling blank diagrams and reciting event flows (e.g., Transcription steps).

## 🚀 Using the `/spaced-schedule` Command
Submit your study topic to get a calculated calendar:
- **Input:** `/spaced-schedule chemistry "Aldehydes & Ketones" 2026-05-10`
- **Output:** A personalized calendar with exact dates for your Day 1, 3, 7, 14, and 30 reviews.

**Senior Sibling Tip:** Don't skip the **Day 3** review. It is the most critical point where the brain decides whether to move information into Long-Term Memory or delete it.
