Try to be punctual if you ask a question in a lecture, identify yourself first - it helps lecturers to know who they are talking to don't sit at the back of the lecture, yawn, gaze out of the window or chatter. Again, you identify yourself for the wrong reasons be responsive in tutorials - don't make the tutor do all the work. If you don't respond they don't know how to help you. Give them feedback Treat tutors as human beings thank them for things they do which help you - this will encourage them to do more of the same. You can thus train them to help you.
Tutors can get defensive too.
Help them to help you. This stimulates academic discussion. Pugnacious, 'personal' unsupported viewpoints are a different matter, as is slavish devotion to their views. However, being polite, considerate, helpful, but your own person can only be perceived as positive. Sussex Language Institute 1998.
