There are times when you find yourself unable to work out a problem. It is at this 28 that the way in which you use your teacher is important. With a good teacher, such times should be less 29 than with a bad one; so the worse the teacher, the more responsibility you have for your 30 ! Whatever your luck in this 31 , one thing is most significant and stays the same, whatever the quality of teaching you receive: if there is something you don't understand, you must ask, again and again if necessary, until you do understand it fully. 32 though this may seem, it is 33 unbelievable how many people would rather sit in silent ignorance than admit not understanding. To behave in such a way is the only truly 34 thing a student can do: it's a false form of pride, which is the most useless, damaging quality anyone can have, to say nothing of a student! 35 , regard your teacher as a guide or even a friend and do not sit quietly wondering what he's going on about.
