UPSC Prelims 2027 — What You Need to Know
The UPSC Civil Services Preliminary Examination 2027 is scheduled for 23 May 2027 (Sunday). It is a one-day, objective-type screening exam consisting of two papers:
| Paper | Type | Marks | Counts For? |
| GS Paper I — General Studies | MCQ (100 questions) | 200 | Yes — for ranking |
| GS Paper II — CSAT | MCQ (80 questions) | 200 | Qualifying only (min. 33%) |
Only GS Paper I marks determine whether you qualify for Mains. The IFoS (Indian Forest Service) Preliminary Exam 2027 will also be conducted on the same day using the same papers.
The notification releases on 13 January 2027 and applications close on 2 February 2027 — a window of just three weeks.
UPSC Mains 2027 — What You Need to Know
The UPSC Civil Services Main Examination 2027 begins on 20 August 2027 (Friday) and spans five days. Unlike Prelims, Mains is a descriptive written exam that tests depth of knowledge, analytical thinking, and writing ability.
| Paper | Marks | Nature |
| Essay | 250 | Counts for merit |
| GS Paper I, II, III, IV | 250 each (1000 total) | Counts for merit |
| Optional Paper I & II | 250 each (500 total) | Counts for merit |
| Indian Language Paper | 300 | Qualifying only |
| English Paper | 300 | Qualifying only |
| Total (Merit) | 1750 |
Candidates who clear Mains are called for the Personality Test (Interview) carrying 275 marks, bringing the grand total to 2025 marks.
There is approximately a 90-day window between Prelims (23 May) and Mains (20 Aug 2027) — a critical period that separates serious aspirants from the rest.

Start Your CSE 2027 Preparation the Right Way
With Prelims confirmed for 23 May 2027, you now have a defined timeline to work with. From the current date to the notification in January 2027, you have roughly 7–8 months of uninterrupted preparation time — the most important stretch in the cycle. Use it to build your static GS base, lock in your Optional Subject, and develop a current affairs reading habit.
From notification to Prelims is another 130 days — the final push phase, where mock tests, revision, and current affairs consolidation must be in full swing.
The right guidance from day one makes all the difference. Vision IAS offers comprehensive courses built around the official UPSC calendar, covering everything from GS Foundation to Mains Answer Writing.
