UPSC Exam Pattern: The Three Stages
The first stage, Preliminary Examination (Prelims), serves as a screening test that qualifies deserving candidates for the Mains. It consists of two objective-type papers: General Studies Paper I (merit ranking) and CSAT Paper II (qualifying nature). Both papers last 2 hours each, carrying 200 marks apiece, for a total of 400 marks.
Moving forward, the Main Examination (Mains) forms the second stage. It comprises 9 descriptive-type papers conducted over multiple days. Seven of these papers count toward the final merit, while two language papers (English and Indian Language) are qualifying in nature. The Mains examination constitutes a substantial 1750 marks of the total assessment.
Finally, the Interview/Personality Test represents the third stage, where a panel evaluates candidates’ suitability for civil services. This final assessment carries 275 marks. Essentially, the complete selection process evaluates candidates across a combined total of 2025 marks (Mains + Interview).
Marking scheme and cutoff overview
When you learn about the UPSC exam pattern, it’s also equally important to understand the cut-off criteria. In the Prelims, each correct answer in both papers earns 2 marks, while each incorrect response incurs a penalty of one-third (1/3) of the marks, approximately 0.66 marks. Additionally, the CSAT paper requires a minimum qualifying score of 33% (66.67 marks out of 200).
The cutoff marks vary yearly based on several factors, including paper difficulty, number of serious candidates, and available vacancies. For instance, recent General category cutoffs have ranged between 80-93 marks out of 200 in GS Paper I. Furthermore, UPSC typically calls candidates for Mains in the ratio of 12-13 times the number of vacancies. Similarly, for interviews, candidates are shortlisted in the ratio of approximately 1:2 compared to the final selection number.
This structured UPSC exam pattern ensures that only the most suitable candidates progress through each stage of this prestigious examination, ultimately selecting around 1000 officers from lakhs of aspirants annually.
