B.A

For IAS preparation it would be good if you puruse your BA Public administration. Public Administration is one of the most popular optional subjects for the mains and account for the 50% shares in the final mains result. Infact One of my friends have told me about UPES university of Dehradun which has come up with a special program for students who wants to study BA in Public administration for IAS preparation. This signals that most of IAS aspirants prefer this subject in their BA. You can check out this university as recently one my friend has enrolled for this program in UPES and the feedback i got from her is amazing. University has embedded IAS coaching and test preparation in its regular program so you will not have to juggle between regular studies and IAS preparation.

don't waste time on ethical hacking join T.I.M.E or other classes which are helpful to crack cat exams. and for hacking bro as a security hacker I advised that hacking is like magic its actually for deceiving peoples because it dangerous and also for for very boring but I suggest if u have pacitient and good coding and decoding skills and u know about programing then u can do m.sc but some time its frustrating and if u want to become then do B.tech because there u can study not only hacking even u know about server security at all because ethical hackers create security zones for data or other important information and unethical hackers try to crack your security it's you can see its very difficult and frustrative work.
so I think prepare for MBA it's help for u like,
IT sector.
