Hi Riya

People who wish to crack UPSC, usually choose easy subjects in their undergraduate degree. If you consider any degree as easy for you, Should choose that. Nowadays colleges provide half a day classes for arts and science. So choosing a half a day college will also help you to prepare for your examinations.

• B.A. in Languages/History/others
• B.Sc degree without labs 

These courses will give more time to study. So choose anything based on your interest and prepare well for your competitive examinations.

All the best.
