If you get 99% or top your exams, that is not great achievement. What is greater is that you should possess high qualities. What is more important than having excellent grades is possessing excellent attributes. What are these attributes? You should manage your time. Lead a simple life. Fulfil your promises. Don’t make too many friends. Work hard. Learn to dedicate yourself. Don’t create unnecessary problems nor clash with people. What is of greater importance is to possess these noble virtues. Getting excellent grades is secondary.
