How to Calculate Your Expected Score Using UPSC Prelims Official Answer Key 2026 

As UPSC Prelims Official Answer Key 2026 is out, you can accurately estimate your marks. Remember the distinct marking schemes for both papers: 

• General Studies (Paper I): Contains 100 questions worth 2 marks each. For every incorrect answer, there is a strict penalty of 0.66 marks (1/3rd of the assigned marks). This paper determines whether you clear the Prelims cut-off. 

• CSAT (Paper II): Contains 80 questions worth 2.5 marks each. The negative marking is 0.83 marks per incorrect answer. This paper is purely qualifying; you must score at least 33% (66 marks) to pass, regardless of your GS score. 

UPSC Prelims 2026 Expected Cut-Off Trend

The expected cut-off for the UPSC Civil Services Preliminary Examination 2026 is likely to be lower than that of the previous year, due to the relatively difficult and time-intensive nature of GS Paper I. CSAT was also considered lengthy and moderately difficult by many candidates. 

Current estimates suggest that the General category cut-off may lie in the range of 80±5 marks, with some variation possible depending on overall candidate performance. Based on present trends, a score of 90+ may be considered relatively safe, while 95–100 marks would place candidates in a much more comfortable position. Overall, a moderate decline in the cut-off is anticipated this year. 

UPSC Prelims 2026 Result 

The Prelims result is expected within a few weeks, but the Civil Services Mains Examination is already officially scheduled to begin on August 21, 2026.
