+### 📚 How to Study This Summary Effectively
+
+Here are some proven techniques to help you learn and remember the material better:
+
+- **Active Recall** — Cover the summary (or close your eyes) and try to explain each main point in your own words. This is one of the most powerful ways to strengthen memory.
+- **Spaced Repetition** — Review this summary today, again in 2–3 days, then in one week. Use free apps like Anki or Quizlet to turn key points into flashcards.
+- **Feynman Technique** — Pretend you're teaching this topic to a friend (or a 12-year-old). Explaining it simply reveals what you truly understand.
+- **Self-Testing** — Create 3–5 questions from the summary (e.g. “What is…?”, “Why does…?”, “Give an example of…”). Answer them without looking.
+- **Make Connections** — Draw a quick mind map or diagram linking the main ideas together. This helps see the big picture.
+- **Apply It** — If possible, solve related problems, write a short paragraph, or discuss the topic with someone.
+
+Re-reading alone is weak — **active engagement** is what makes information stick!
+
+Good luck with your studies! 🚀
