📖 How to Use These Notes

Read once for conceptual clarity, then revisit with current affairs integration. S&T questions in UPSC are 80% current-affairs-linked — whenever a new technology makes news (ISRO launch, DRDO test, new vaccine), link it back to the relevant chapter in these notes. For non-science aspirants: focus on “what it does” and “India’s relevance” rather than technical details.
