UPSC Civil Services: A Beginner's Guide

The UPSC Civil Services Examination (CSE) is the gateway to becoming an IAS, IPS or IFS officer — the most prestigious career route in Indian government. It is also one of the toughest exams in the world, with lakhs of applicants for a few hundred to a thousand posts each year.

If you are just starting out, this guide explains what the exam is, who can apply, how the three stages work, and what a realistic preparation looks like. Exact dates, attempts and scheme details change each year, so always confirm against the official UPSC notification on upsc.gov.in.

What is the UPSC CSE and which services does it recruit for?

The UPSC CSE recruits officers for around two dozen services. The most sought-after are the All India Services — IAS (administration) and IPS (police) — followed by Group A central services like the IFS (foreign service), IRS (tax) and audit/accounts services, and some Group B services. Your final service depends on your rank and your stated preferences.

Eligibility, age and attempts

• Education: a bachelor's degree in any discipline. Final-year students can attempt the Prelims but must show proof of graduation before the Mains.
• Age: 21 to 32 years for the General category (as on the cut-off date), with the upper limit relaxed to 35 for OBC and 37 for SC/ST, and more for PwBD.
• Attempts: 6 for General, 9 for OBC, and unlimited (within the age limit) for SC/ST.
• Nationality: Indian citizenship is required for the IAS and IPS.

The three stages

The exam has three stages spread across roughly a year:

• Prelims (screening only): two objective papers on the same day — General Studies Paper I (200 marks, decides the cut-off) and CSAT Paper II (200 marks, qualifying at 33%). Prelims marks do not count toward your final rank.
• Mains (written): nine papers — an essay, four General Studies papers, two optional-subject papers (all counting toward merit), plus two qualifying language papers (English and an Indian language).
• Personality Test (Interview): 275 marks, assessing your suitability for public service.

The optional subject and final marks

You choose one optional subject (two papers, 500 marks total) from UPSC's defined list of around 48 options — about 25 academic subjects plus the literature of various languages. The final merit is based on the Mains merit papers (1750 marks) plus the Interview (275 marks), a total of 2025 — the Prelims and the qualifying language papers are excluded.

Salary

Officers enter at Pay Level 10 (basic pay ₹56,100), with gross pay roughly ₹80,000 to over ₹1 lakh a month including allowances. Pay rises steadily through the career — Senior Time Scale, Junior Administrative Grade, and up to the very top posts in government — making it one of the most rewarding long-term careers in the public sector.

A realistic preparation overview

There is no single right way to prepare, but a common framework for a first serious attempt looks like this:

• Plan for roughly 12–18 months of focused study, adjusted to your background.
• Build a foundation with the NCERT textbooks (classes 6–12) across History, Geography, Polity, Economics and Science before moving to standard reference books.
• Read a newspaper daily and follow monthly current-affairs compilations — current affairs runs through both Prelims and Mains.
• Choose your optional subject early, and practise answer-writing regularly — the Mains is descriptive, so writing speed and structure matter as much as knowledge.
• Take regular mock tests — objective tests for Prelims and answer-writing practice for Mains.

When is the exam held?

The cycle runs roughly: notification around January–February, Prelims around May–June, Mains around August–September, interviews in the following months, and final results about a year after the Prelims. Treat these as typical and confirm the year's exact dates in the official notification.
