Hi,

Yes you can write your optional paper in English. As per my knowledge there is only one compulsory section of Hindi. Mostly, you will be allowed to do your exam in Hindi except where English is compulsory as it is a state civil service Exam.

I would like to tell you, BPSC give you chances to choose your language, you can choose any one language for mains exam, which is valid for all papers. Means, If you choose English Medium you would write each paper in English. You can't use two languages in different papers.

Candidates will have the option to answer all the question papers, except the Qualifying Language Papers, in any one of the languages included in the Hindi or in English. Not with standing this, the Candidate will have the choice to write the Optional Papers in English also if candidates opt to write Paper I-V except the Qualifying Language Papers, Paper-A and Paper-B, in any one of the language included in the Hindi.

Hope this helps.

All the best,
