Hello

To become an IAS officer you need to clear UPSC.

First of all you cannot do graduation from NIOS

This is because,

NIOS is an open school so it offers only education upto 12th.

But yes,

If you want to do graduation in open mode then you can do it from open universities like IGNOU .

UPSC eligibility  criteria is provided below:-

******** You  must  have  a  bachelor's  degree in any, discipline    from a recognised university.

†††† So, even if one does graduation from open universities he is eligible for UPSC provided it is recognised one like IGNOU.

******** Minimum  age  limit :-  you  need to  be at least  21  years  old   to be  eligible as on 1st of August of the year of filling the form

******** Maximum  age  limit :-  32 years , also there's 3  year  relaxation on upper age limit for  obc and of  5 years  for sc/st category.

†††† Now with your date of birth on 2nd October 1991, right now you are over 29 years old and graduation is of 3 years so by the time you will complete graduation you will be over 32 years old and thus not eligible for UPSC if you belong to general category. But  if you belong to obc/sc/st then you are eligible and after qualifying upsc you can become an ias depending upon your rank in upsc.
