UPSC Prelims Answer Key 2020 - Important Points

  • UPSC prelims answer key is prepared by NeoStencil with the help of Top IAS coaching institutes in Delhi.
  • For each question, answers are given with source and reference links to attain accuracy.
  • UPSC Answer key is helpful for students to determine the expected marks on each section of the paper and based on which, they can start their preparation for next level of IAS exam.

UPSC does not use the terminology cut-off marks in their press releases; instead, they mention minimum qualifying marks. The minimum qualifying limit is determined based on the score of the preceding year IAS exam for each category. Say for example: if there are 400 vacancies in general category, then the mark of the 400th general candidate s marks will become the cut-off marks of general category. So, there is no workable methodology or statistics to calculate the cut-off marks.

The minimum qualifying marks (cut off marks) for each level of examination i.e., Prelims, Mains and Final selection is released by UPSC after the final recommendation list. But students, who appeared for the prelims exam, will be eagerly waiting whether they are eligible or not for the mains examination. To offer help, many institutes predict the expected cut off marks based on their experience and careful analysis.
