What should be the proirity of subects?

We have segregated the subjects of the prelims into three levels of priorities as per Law of 40:40:20 (click here to know about this law).

Priority 1(First 40): These are those subjects, if you prepare them extremely good, then no one can stop you to clear this exam whenever you appear. The questions from these subjects should be the Sure-shot Correct Questions.

Priority 2 (Second 40): These are the subjects which are to be studied and also with dedication as they will act as supporting hand in case of any weakness in Priority 1. It will also act as the “Elimination Type Questions”.

Priority 3 (Third 20): Least cost benefit ratio subjects. Least scoring subjects, just do basics. Most of the questions from this sections may go wrong and can pile up huge negative marks.
