The syllabus for optional subjects in the UPSC can greatly influence a candidate’s choice. Aspirants often select subjects based on interest, background knowledge, and perceived scoring potential. Those with a strong foundation in a particular subject may opt for it, believing it could leverage their existing understanding. However, the perceived syllabus length and complexity also play a crucial role; candidates may avoid overly extensive or obscure subjects. In essence, candidates must consider both their strengths and the syllabus demands when making their final choice.
