Calculate your score :

Aspirants can also calculate their UPSC Prelims 2021 score with the help of JV’s answer keys. 

  • In both GS (Paper 1) and CSAT (Paper-II), there will be negative marking. 
  • Every question carries two marks; so if an aspirant answers a question correctly, he/she will be rewarded with two marks. 
  • For every incorrect answer, UPSC deducts one-third of the 2 marks allotted to question ie. 0.67 marks.
  • For example, if an aspirant attempts 85 questions out of which 60 questions are correct and 25 are wrong.
  • Then his/her expected score would be (60×2 – 25×0.67), i.e., 120 – 16.75 = 103.25 marks.
