How to Apply

The application is an online form on the UPSC’s online application portal. Everything below is done in one sitting or saved and returned to; nothing is done on paper.

1

Register

There is no separate application for the Main examination in the ordinary sense — qualified candidates fill a Detailed Application Form on the Commission’s portal within the window announced with the Preliminary result.

2

Fill the form

The Detailed Application Form asks for the full record: education, employment, the optional subject, the language chosen for the papers, and the centre. It is the document the interview board reads from, so what is written here is what you will be asked about.

3

Choose test cities

Cities are given in order of preference and allotted on availability, so the first choice is not guaranteed. Pick somewhere you can reach the morning of the exam without an overnight journey.

4

Upload photograph and signature

Both have to meet the format, size and background stated in the notification. A rejected upload is the most common reason a form is left incomplete past the deadline.

5

Pay the fee

Online, through the official portal only. The amount is set afresh in each year’s notification and is lower for SC, ST and PwD candidates. Keep the payment receipt.

6

Submit, then check

Print the completed form. A correction window usually opens afterwards -- it is limited, and it rarely covers every field, so it is a repair, not a second chance.

Apply only through the official portal. No agent can register you, and nobody can change a score once it is declared.

Selection Process

Nine papers are written. Seven of them count.

PaperWhat it is
Paper A — Indian LanguageQualifying only. Marks do not count towards the merit list, but failing it means the rest of the papers are not evaluated.
Paper B — EnglishQualifying only, on the same terms.
EssayCounted.
General Studies I to IVCounted. Four papers covering heritage and society; governance and international relations; economy, environment and security; and ethics, integrity and aptitude.
Optional Paper I and IICounted. One subject chosen from the Commission’s list, written as two papers.

The written papers are descriptive, not multiple choice. Candidates who clear the written stage are called for a Personality Test, and the final merit list is struck on the written marks and the interview together — the Preliminary marks play no part in it.
