Civil Servant (IAS/PCS)

To become an IAS officer, you basically need a UG degree and more over age limit is the main constraint. You need to complete or attempt for IAS exams before the age limit crosses. After your UG I would suggest you to get through the right institution which provides IAS coaching. A proper academy with an experienced person training. This will give you overall exposure about the examinations and other process of the examinations. They will even help you in how to study the syllabus in short span of time. People advised me as a student to study 18hours daily to clear IAS successfully. So I would suggest you start reading books and try gaining knowledge from now to make it easy during the examinations. So more you prepare the better your results are. So I wish you all the best for your dreams. I hope this is clear. Thank you.

You must graduate. Graduation is a must. Here are few things you can do, and DO adjust or modify them as per your own convenience :)
During your graduation years, revisit NCERTs and read all class 6-12 NCERTs (Social Science, History, Geography, Science) and develop an understanding of basics. ( For class 11-12 NCERTs, read selectively, I might answer how selectively in another answer)
Develop the habbit ofNewspaper Reading. Start by any simple newspaper, The Indian Express for example. No notes making. Remember you're just developing the habbit of reading. And during newspaper reading sit with a mobile with google search and google whatever news, its context, terminology, etc. You don't understand, as much as you can, but till a limit because graduation ki padhai bhi hai. When you get comfortable switch to The Hindu. Daily listen to AIR news, 15 min in morning (8.00 am for Hindi, 8.15 am for English ; and 15 min in night (9.00 pm for Hindi, 9.15 for English I think) the easiest way to revise major current affairs. If you have access to TV then news at 9 on DD news is also good. Develop an inqusitive mind. That's it. Developing basics by NCERTs
and understanding your surroundings and whats going on in your society, you country, your world, through current affairs. That'll be a LOT to achieve if you can in your graduation years.
