Yes! Now UPSC provides options to write GS and Optional papers in different mediums (Since 2018). If you choose to write GS and Essay papers in Hindi and Optional Paper in English you can do so. But point to be noted here is, If you choose to write GS and Essay papers in English then you have to write Optional papers also in English. It means, given the technical/subject specific terminology in optional, you are given opportunity to write it in English while writing GS papers in your fluent or compatible language.

You will get these option while filling the application form for prelim. UPSC ask optional subject and medium both for GS & Essay papers and Optional subject separately in the preliminary stage itself. So, you get sufficient time to get yourself ready and mater in the chosen language.

Further, If you write your GS papers in English medium and want to choose Hindi for interviews that option is also available. But that is not vice versa, that is if your medium for mains is Hindi/regional languages, you can not opt English for Interview.

So, Go ahead without any hesitation or concern if you are more comfortable for Optional to write in English and confident for GS and Essay papers to write in Hindi or any other regional languages (VIII Schedule langues). All the best!!!

No,

But UPSC from year 2018, started allowing candidates to choose their language choice for the five subjects (Essay + 4 GS Papers) separately and Language for Optional language Separately.
