UPSC Exam Pattern- UPSC Exam Pattern for IAS

For any aspirant to succeed in the UPSC Exam, they must have a comprehensive understanding of the UPSC Exam Pattern. The UPSC selection process can be broken down into three stages: Prelims, Main, and Personality Test or Interview Round. Every year, 12-15 lakh candidates appear for the exam, but only about 1000 get selected after a rigorous selection process, thus making UPSC one of the most competitive exams in India. 

The Prelims Round is qualifying in nature, while the scores of the Mains and the Interview Rounds count towards the final merit score and ranking of a candidate. A candidate’s total merit score is given out of 2025 total marks, based on a combination of the score of the Mains and the Interview. Read on to know the detailed UPSC Exam Pattern.

Frequently Asked Questions

To qualify in the UPSC Prelims, a candidate must meet the cutoff in the GS Paper I, and get at least 33% or 66 marks in GS Paper II (CSAT). Failing to meet either of these criteria will result in the candidate not qualifying for the UPSC Main.

No, the UPSC Prelims Marks do not count in the final merit score or the final ranking of a candidate. Only a candidate's total score of the Main and Interview, which makes up a total of 2025 marks, is considered for their final marks and ranking.

The UPSC selection process is rigorous, consisting of 3 rounds:

  1.  UPSC Prelims
  2. UPSC Main
  3.  Interview or Personality Test round. 

A candidate must qualify in the UPSC Prelims, appear for the Mains, and then the Personality Test round. After this, the candidates are ranked based on their final scores (a sum of their Main and Personality Test Round scores), and the ones holding the highest ranks are allotted their desired positions.

The total number of attempts allowed in UPSC varies based on the category to which a candidate belongs. 

  1. General category: 6 attempts till age 32. 
  2. OBC: 9 attempts till age 35. 
  3. SC/ ST: Unlimited attempts till age 37.

No. Simply registering doesn't count as an attempt. Candidates must appear for at least one UPSC Prelims paper for it to be counted as an attempt.
