Assuming we have 80 days left (forgoing few days for other activities ) ,we need to be selective in what can be read and revised in these 80 days.Here is a list of books which I am going to follow.I have put this list for those who are not able to decide on their own.Each day i will be posting what i a have read and you can post your progress too ,so that you can keep yourself on track.Those who are preparing alone can stay focused through this.All the best.
