## Calculating score with the help of UPSC Answer Key

Candidates can calculate their UPSC Prelims score with the help of these answer keys. In both GS 1 and CSAT, there is negative marking. For every incorrect answer, 1/3rd of the total marks allotted for that question will be deducted.

- For General Studies I, every incorrect answer incurs a penalty of 0.66 marks
- For General Studies II (CSAT), every incorrect answer incurs a penalty of 0.83 marks.
- The difference is there because, in GS paper 1, there are 100 questions of 2 marks each while in CSAT there are 80 questions of 2.5 marks each.
- In the case of GS 1, the candidates need to score above the UPSC Cut Off for that particular year to qualify for the Mains stage of the Civil Service Examination. Candidates can check the expected UPSC Cut Off 2019 at the linked article.
- Also, the UPSC Cut Off varies depending on the category of the candidates as well.
- The GS 2 or CSAT is a qualifying paper in UPSC Prelims and candidates have to score 33% or above to advance to the Mains stage.
- Candidates should calculate their expected marks based on the UPSC Answer Key given above, and if their marks are close to the average cut off from previous years, then they should start with the Mains preparation.
