1. UPSC Eligibility: Who Can Apply?

The term UPSC eligibility comprises multiple criteria — nationality, age, educational qualification, and number of attempts. Meeting eligibility is the first filter you must clear before focusing on preparation.

1.1 Nationality & Citizenship

• You must be a citizen of India for certain services (e.g. IAS, IPS, IFS). 
• In some cases, candidates from Nepal, Bhutan, or Tibetan refugees (who came to India before Jan 1, 1962 with intention to settle permanently) may apply, subject to a certificate of eligibility from the Government of India.

1.2 UPSC Age Limit

A critical part of UPSC eligibility is the UPSC age limit. For the 2025 cycle:

• Minimum age: 21 years as of 1 August 2025

3. How to Use These Insights in Your UPSC Strategy

Knowing the UPSC eligibility, UPSC age limit, UPSC qualification required, and UPSC exam pattern is not enough — you must integrate them into your preparation. Here’s how:

1. Confirm your eligibility early — don’t invest effort before you’re sure you qualify.

2. Back‑plan from exam pattern — allocate time to mock tests, answer writing, optional subject, etc.

3. Focus on high‑weight papers — GS I, GS II, Optional, and Essay carry bulk of merit marks.

4. Practice negative marking strategies — only attempt questions you’re confident about in Prelims.

5. Polish interview skills — current affairs, personality, clarity of thought matter a lot.
