UPSC Civil Services: exam date, timeline and full structure

When is the next UPSC Civil Services exam?

Both of those dates come from the commission's own annual examination programme, and the note under each says which document and which revision. The Main examination runs over several consecutive days from the date shown; the date stored is the day it begins.

That we can show a Mains date at all is worth pausing on. UPSC publishes a calendar for the following year well in advance, so for most of a cycle both dates exist officially. Many state commissions do not work that way — which is why a page like this one is genuinely easier to write for UPSC than for a state PCS, and why you should be more suspicious of a confidently-stated state Mains date than of this one.

How one UPSC cycle runs

1. The annual examination calendar fixes provisional dates for every examination UPSC conducts that year.
2. The detailed notification for the Civil Services Examination appears, carrying eligibility, the vacancy count and the application window.
3. The online application window opens and closes.
4. The Preliminary examination — two objective papers on a single day.
5. The Preliminary result decides who writes the Main examination. Prelims marks do not enter the final merit list.
6. The Main examination — nine written papers over several days.
7. The Main result, then the Personality Test (the interview).
8. The final merit list.

The full structure, paper by paper

"Qualifying" means three different things here, and confusing them is expensive

This is the single most-flattened fact about this examination. Pages describing it tend to use one word, "qualifying", for arrangements that behave completely differently:

A stage gate. The Prelims CSAT paper has a percentage threshold. Miss it and your candidature ends at the Preliminary stage — your General Studies score is irrelevant, however good it was.

An evaluation gate. The two Mains language papers also have a threshold, and the consequence is stricter than the word "qualifying" suggests. Fall below it and your remaining written papers are not evaluated at all. Not scored low — not read. A candidate can write an excellent Essay and four strong General Studies papers and have none of them opened, because of a paper that contributes nothing to their rank.

No minimum at all. The Personality Test carries no qualifying threshold. It is pure merit marks.

If you take one thing from this page, take the middle one. It is the difference between a paper you can safely deprioritise and a paper that can silently void everything else you wrote that week.

Where the marks actually are

Read that alongside the pattern table. The qualifying block is real marks, real papers and real exam days that contribute exactly nothing to your position in the list — while remaining perfectly capable of ending your attempt. Meanwhile the optional subject you choose is answered across two papers of equal weight, and both papers must be that same subject.

What the notification deliberately does not fix

Two numbers everyone quotes are not in the official notification at all, and we mark them as not notified rather than printing the customary figure:

• The number of questions in each Preliminary paper. The notification fixes the marks and the duration. The familiar counts are what past papers have carried, which is a description of practice, not a rule — and a rule is what a candidate planning their timing thinks they are reading.
• The Prelims-to-Mains shortlist ratio. Widely quoted, not fixed anywhere.

Two further conditions in the official notes are worth knowing because they change who has to sit what: the Indian-language paper does not apply to candidates from certain north-eastern states or to certain hearing-impaired candidates with benchmark disabilities, and candidates with specified disabilities receive compensatory time — so the duration in the table is not the same for every candidate.

Where to go from here

The structure tells you what the exam is. It does not tell you what it asks. That is a separate question, and one worth answering from eleven years of real papers rather than from received wisdom.
