Law of averages is fundamental in the population distribution pattern of all living beings in nature towards any character. In this, the most population of any species trends towards average in consideration of any characteristics.
In simple words the theory is that most people fall in average category for any character let it be hight, weight, intelligence or anything similar.
If so, then what makes anyone to excel at a point of time? It is little extra effort over the average that singles out a person from the crowd.
Remember, therefore that little extra effort is always required in order to become a winner in any walk of life. The same is true in cracking ICAR admission test too.
