How to Choose the Best Optional Subject While Filling the Form

Factors to Consider

Your optional subject can seriously boost – or hurt – your final score. Think about:

  • A subject you enjoy or have studied before
  • Syllabus length and past scoring trends
  • Availability of quality study material

Popular Optional Subjects

Sociology, public administration, PSIR, geography, and history are most popular. Sociology and PSIR have shorter syllabi, which is why many toppers prefer them.

Mistakes to Avoid

Don't copy your friend's choice. Don't rely only on YouTube videos. Research properly, then decide.
