In the UPSC Mains exam, the weightage of optional subjects is significant, as they comprise one of the key components of the assessment. Each optional subject typically consists of two papers, with a combined maximum score of 500 marks. This weightage allows candidates to leverage their strengths in subjects they are passionate about, helping to enhance their overall ranking. The performance in the optional papers can substantially influence a candidate’s total score, thereby determining their chances of success in the examination. Selecting the right optional subject can, therefore, be a pivotal decision for aspirants.
