Can I get selected in a PSC exam other than my state?

Yeah you can selected in any states PSC exam doesn’t matter it is your domicile state or not.

But the condition is this that you need to pass a language exam of that particular state with minimum passing marks and that passing marks may be 33% or 30% or 40% or 25% or something else according to state.

Ex. lets take you are a resident of Uttar Pradesh and you want to give exam of Rajasthan, Haryana, Uttarakhand so for this you need to pass a exam of Hindi language but if you want to give exam of Kerala then you need to pass exam of Malayalam same like in case of Gujarat it will be Gujarati language.

How many states in India conducts state psc exam and frequency of that exam?
