Hello Muhammad,
I am very glad to see an aspiring IAS student. After intermediate, you should puruse a Bachelor's degree in public administration, political science or history. History is preferable because it will help you to crack the exam easily. You need to keep yourself updated by reading newspapers and make a note of current affairs. I'll suggest you to join a reputed IAS academy because it will show you an easy map to your goal.
All the best.
God bless you.

You should opt for arts in HSC. You can pursue BA in graduation as BA will be the right option and once you complete BA, you can start preparing for IPS, you will definitely get through the exams if you really work hard.

Yes. There is no such restrictions, eligibility to write a IAS exam is under graduation which you have completed. Please go for it.

Hi Devesh,
According to me, you should begin with your preparations from the 3rd year. Till then studies are easier comparatively. You'll be able to score well enough for any competitive exams till 2nd year if you concentrate on B.Com. Only till then.
Rest you know yourself better. If you feel like you are capable enough to manage the additional coaching other than your current study matter, then go ahead.
Good luck.
