Best Optional Subject for UPSC

No optional subject is easier for UPSC. The skill, learning ability, and interest of a candidate determine which optional subject would best suit him/her. However, candidates should choose an optional subject with easily available study material.

  • According to the most recent patterns for the UPSC civil services exam, the weightage of the optional subject is 500 marks out of 2025 marks.
  • This is an integral factor in determining the final ranks. You need to choose the best scoring option for UPSC to help you fetch maximum marks.
  • There are many parameters to choosing the Best Optional Subject for UPSC, such as the knowledge of the subject and the availability of study materials.
  • Most of the candidates opt for a subject they choose at graduation. But it is not the constant or only factor deciding the Best Optional Subject for UPSC.

Most Opted UPSC Optional Subject

A scoring subject and the Best Optional Subject for UPSC are two different things. Candidates can score big in every subject as per past records.

  • But some subjects are perceived as low scoring because the candidates cannot put in the requisite effort or they have chosen an optional subject that is not right for them. And this is when the concept of the Best Optional Subject for UPSC comes into the picture.
  • Technical subjects like mathematics can fetch you high marks because there is an absolute answer to each question. In comparison, humanities subjects depend on the examiner’s preferences.

  • But it doesn’t mean the candidates can’t score well in these non-technical subjects.
  • The non-technical subjects that overlap with the GS syllabus offer an advantage to the candidates as they will get more time for preparation and reading materials. This will help the candidates to boost their overall Mains score.
