# Distributed System

**Total Days if Complete Newbie:** 5.5 days

- **4 days** to understand all topics
- **1 day** for revision (aim to revise 3× before the exam)
- **0.5 days** buffer for error adjustment

**Study Sequence:**
1. Skim all chapter titles for 5 min to get familiar
2. **Chapter 2 & 8** first (1.5 days)
3. **Chapter 5 & 6**, then **7** (1.5 days)
4. **Chapter 1, 3 & 4** (1 day)
5. Revision of individual topics (1 day)

> A very good way to revise before exam is to play the YouTube videos at **1.25×–1.5×** speed, then review your notes.
