Academic achievement is not the only measure to decide a person's success in life. A human being needs to play many roles in his life to be called a complete man. He should be successful in many ways as a son, husband, brother, and as a constituent of a large human family of this earth. The academic record is only one part of a man's achievement. He has many responsibilities and obligations towards human society.
Gaining knowledge is not the only important thing in a person's life, but he should use that knowledge for the welfare of his fellow beings and the society as well. Along with brainpower, he must have humanity and compassion towards his fellow beings. All the human knowledge of this world has only one aim i.e. making human life better.
