How to decide in one week
- Read the official syllabus of all three side by side.
- Read the last three years' question papers and ask which ones you could imagine answering.
- Read one standard chapter of each — the one you finish without forcing yourself is a good sign.
- Check your background: medical and science graduates often find Anthropology's physical section easy.
- Ignore toppers' lists — one year's toppers do not predict next year's scores.
Common mistakes when picking an optional
- Choosing purely because of 'scoring' reputation.
- Changing optional after one attempt without a clear reason.
- Starting the optional only after Prelims — it needs steady work through the year.
