Hello Aspirant,

Union Public Service Commission (UPSC) conducts different examination for different fields like for engineering there is ESE, for administrative services there is IAS exam, for Foreign Services it has IFS exam and likewise for other fields also.

For different fields different subjects knowledge is required and as you have not mentioned for which exam you want to appear which is conducted by UPSC so it is little bit difficult to guide you accurately with the list of subjects.

However you can get the list of UPSC approved subjects for different fields from the PDF file whose link is given below :-

I hope this information helps you.

Good Luck!!
