UPSC Exam Pattern – IAS Prelims, Mains, CSE Paper Pattern, Total Marks

The Union Public Service Commission (UPSC) conducts the Civil Services Examination (CSE) annually to select candidates for prestigious services like the Indian Administrative Service (IAS), Indian Police Service (IPS), Indian Foreign Service (IFS), and others. The UPSC CSE is one of the most competitive exams in India, and understanding its structure is crucial for efficient preparation.

The UPSC exam is conducted in three stages:

1. Preliminary Examination

2. Main Examination

3. Personality Test (Interview)

Candidates must clear each of these stages to move on to the next. The Prelims and Mains stages are both elimination rounds, while the Interview/Personality Test is the final assessment before the final merit list is declared.

Stage 1: UPSC CSE Exam Pattern for IAS Preliminary Examination

The Prelims is the first step of the examination process and is a screening test. It comprises two papers:
  • Paper I: General Studies (Objective-type)
  • Paper II: CSAT (Civil Services Aptitude Test)
While CSAT (Paper II) is qualifying in nature, your performance in General Studies (Paper I) is crucial as it will be used to determine your eligibility for the Mains. Negative marking is applicable, with a penalty of 1/3rd of the marks for each wrong answer.

Stage 3: UPSC CSE Interview/Personality Test

This is the final stage of the IAS Exam before the final results are declared. Officially it is called the Interview/Personality Test and counted as a part of the Mains Examination for merit ranking purposes. From a preparation standpoint, it is considered the third stage as preparation strategies for the written and interview stages are different. As per the IAS exam pattern, this consists of an interview by the UPSC board to assess the candidates’ suitability for a civil services career and associated responsibilities. The board consists of competent and unbiased observers who have a record of the candidates’ career. The board would judge the candidates mental and social traits by asking questions of general interest. Some of the qualities that the board looks for are mental alertness, critical powers of assimilation, clear and logical exposition, a balance of judgement, variety and depth of interest, ability for social cohesion and leadership, intellectual and moral integrity.
