It is “your responsibility” to find more information and v already shown u the right direction. In NZ universities, tutors r using this attitude to teach students. They only show the directions to students & students should continue their own reseaches. It is ur responsibilities to do further researches, not us! Remember v r only “volunteers”. I never see u r a maturer person simply because u r showing me u r very demanding, lack of critical thinking, proper studying & humble attitude! Sorry! V already reached our limit. I think I've done enough! If u cannot go any further, DO NOT PUT THE BLAIM ON US! If u dislike this way of learning & culture, AUSTRALIA AND NZ DO NOT SUIT U!
