Sir you told me not to join coaching institutes before my graduation but can i read all those books which you have mentioned for gs 1,2,3,4. And secondly i want to know that as upsc has changed the exam pattern whether upsc also changes the syllabus contents annually . Sir i have one more problem. I have made my mind about choosing public administration for my future optional subject and naturally i would give more importance to it in my graduation but if at that time upsc announces that know there will be 2 optionals to choose. How one can tackle that problem. Sir i am really really inspired from your hard work which you are doing for the upsc aspirants. I am very enthusiastic about becoming an ias and i hope you help me clear all my answers as soon as possible.
