Hello,

Hope you are doing well.

As per your query, it is not possible to write all the GS papers in Regional Language and write your Optional in English language.

The Candidates have the option to write their answers either in English or in any one of the Eighth Schedule languages except the Qualifying Language papers Paper-A and Paper-B, which they have indicated at the time of filling up of their online application form for the Civil Service (Preliminary) Examination.

Hope this clears your doubt. All the best!
