Tutor- Source of inspiration or irritation?

Starting a blogId was a long time proposal, atlast I have suceeded. I am Ponnarasi doing my 3rd year graduation. I reside at Chennai,Tamilnadu. This week we had our semester lab exams. For the second time same external came, who hardly knows how to behave in front of students. I am still wonder'g how he is being employed in Sathyabama.
I guess, a tutor should be a source of inspiration, but this one ah...is a source of irritation. He suppresses and hurts everyone by giving unwanted comments. Still more surprising why he is being called semestr aftr semester. Worst part of the story is he has published few books which contains only,'is,or,this,that' and few technical terms. I really cud'nt make out how our teachers cud take such insults, bcoz i guess these are insults not only to the students but also to the Institution and the academicians employed.Life is afterall full of experiments or experiences, he has taught us a lesson, none of the 63students including me will dare to hurt any1 in future. 1billion dollar question is,"does he really has some matter or is a empty vessel?" Guess I will turnup the next time with some pleasant issues.
