As a School Student, I have always wondered why certain things, especially in Mathematics, are taught without explanations ? And why Some Teachers are not able to Teach even though They are Teachers ? Maybe They do not Try their Best ? These questions stayed in the back of My Head since then...and I remember promising Myself: "If I am ever gonna Teach Someone, I am going to make Sure that I teach to share Knowledge, not so that He or She memorizes concepts to pass the Exam" ! And I hope to hold that Promise !
