Hello,

The basic criteria to appear in UPSC exam is passed graduation in any discipline from a recognized university, if you're going to pursue Political Science(Hons) then it's a pretty good choice as there is overlapping of GS syllabus and you can have it as optional as well which has syllabus equivalent to graduation level study itself, hence it's a great choice, to pursue integrated course or not is dependent on what are your career plans, as in if you're looking to have a career in academics or research other than UPSC then you can explore this option, otherwise as I said to appear in UPSC only a graduate degree is needed from a recognized university, pursuing master degree is your choice, it's not a compulsory criteria.
