Hey,

You are not prohibited from writing your Mains paper in your regional language by the Union Public Service Commission. Gujarati is an important part of the 8th timetable, and you can use it to write your responses for the GS papers. However, you should keep in mind that this only applies to the Mains and Interview. Initially, you will not be able to select a paper in your preferred language. Along with that, you must write in English in your English paper.

i hope it hels.

Regards
