Negative Marking in UPSC IAS 2025

There is a negative marking in the UPSC IAS prelims exam. The candidates need to be very careful while answering the questions because negative marking can reduce their score sharply. There is a negative marking of (1/3). It means (1/3) marks, of the assigned marks to the questions, will be deducted for the wrong answer. No marks will be deducted for the questions left blank by the candidates.
