Can I use the UPSC Prelims 2023 paper for current practice?
Yes. PYQ revision is one of the highest-yield activities for current aspirants. UPSC reuses themes and concepts every few years, so working through 2023 questions sharpens both content recall and the elimination strategy that UPSC's MCQ format rewards.

UPSC accepts written objections to its provisional answer key during a fixed window each year. A small number of questions across most years are dropped or have answers changed in the final key — the version shown above reflects UPSC's final accepted answers.
Is CSAT counted in the Prelims cutoff?
No. CSAT (Paper 2) is qualifying only — you must score 33% (66 of 200 marks) to qualify, but the merit cutoff is decided entirely by GS Paper 1 marks.
