UPSC is called the toughest because it’s not just about studying a lot. You’re competing with lakhs of people who are all working really hard. The syllabus is huge, and you need to remember things from Polity, History, Economy, Current Affairs — everything. It’s like preparing for 10 different exams at once.

Even if you know everything, you can still fail because the questions are unpredictable. You might clear Prelims but get stuck in Mains. Or do well in Mains and mess up the interview. One small mistake and you’re out — and you have to wait a whole year to try again.

Also, it takes years — not months. You have to stay motivated through failures, delays, and uncertainty. That’s why people say it’s the toughest. It’s not just about brains — it’s about patience, consistency, and mental strength.
