Common Mistakes to Avoid

• Reading Too Many Books: Stick to limited quality resources. Reading 10 books on one topic is less effective than reading 2 books thoroughly.
• Neglecting Current Affairs: Current affairs is not a separate section - it integrates with all GS papers.
• Ignoring Answer Writing: Mains is about articulation, not just knowledge. Start writing answers from month 3.
• Inconsistent Newspaper Reading: Daily newspaper reading is non-negotiable. Don't try to cover it through monthly compilations alone.
• Over-Reliance on Coaching: Coaching guides you, but self-study is irreplaceable. No coaching can substitute for your own effort.
