Master Basic Science Concepts for UPSC Prelims & GS Paper – Fast & Simple Guide

1. Start with NCERT Basics: Class 6–10 NCERTs build clarity in Physics, Chemistry, Biology. (Focus on definitions, diagrams & everyday applications.)

2. Learn Through Real-Life Examples: Relate concepts like pressure, gravity, acids–bases, vaccines, satellites to daily life. (This boosts retention & understanding.)

3. Focus on High-Weightage Topics: Biotechnology, Space Tech, Energy, Environment–Biology, Nuclear Science, Basics of Physics & Chemistry

4. Make Concept Maps: Summarize each chapter in 1 page. (Use flowcharts for cycles, processes, mechanisms.)

5. Revise with PYQs: Solve last 15 years Prelims questions. (Identify patterns + repeated concepts.)

6. Use Govt Sources: ISRO, PIB, MoEFCC, Science Reporter for current developments.

7. Practice Quick Notes & Flashcards: Ideal for formulas, terminologies, inventions, key scientists.

8. Weekly Revision- Every Sunday revise: => NCERT notes => Current affairs science => PYQ concepts

9. Avoid Over-Reading: Stick to basics; UPSC tests understanding, not depth.

10. Integrate Static + Current: Link concepts like mRNA, Li-ion batteries, CRISPR, quantum tech with theory.
