Hello,

Yes, you can write the general studies paper in the Gujrati language. It is allowed to write the exam paper on any of the scheduled languages of India and gukrati being the mother tongue of Gujarat people. So, it is allowed totally.

As Gujarati is an optional subject in UPSC exams. A candidate is allowed to write answers in the Gujrati language without any issues. Along with this, you can also access the Gujarati literature syllabus as well. You might feel some issues if you are not in the language you need to convert every sentences and every word into Gujarati. If you know well then you can write okay!

For any query revert here, you are most welcome!

Thank you and good luck!
