Lesson Structure
Every lesson follows the same format:
- Visual introduction — The core concept in one diagram
- Main content — Explained as: diagram → conclusion → details
- Worked examples — Revealed step by step
- Quiz — 4–8 questions, instantly graded
- Exercises — Two levels: Basic and Standard (entrance exam level)
Progress Tracking
- Press the “Mark complete” button at the bottom of each lesson to save your progress

Color Legend (Consistent Across the Site)
Colors carry consistent meaning throughout this site:
| Color | Meaning |
|---|---|
| ■ Red | Oxidation / Anode / Exothermic |
| ■ Blue | Reduction / Cathode / Endothermic |
| ■ Green | Correct / Complete |
| ■ Yellow/Orange | Caution / Key point |
Information is never conveyed by color alone — labels and icons are always provided (universal design).
Tips for Effective Study
- Look at the diagram first — try to understand the figure before reading the text
- Try examples yourself — think before pressing the step reveal button
- Always do the quiz — don’t skip it. Reading explanations for wrong answers is the most efficient way to learn
- Progress through exercises — master “Basic” before moving to “Standard”
