Thought of a few more!Argue/debate minutiae with the lecturer in your own time, not during the lecture.
I'm not a lecturer/teaching professional myself, but I'm pretty sure they (and everyone else!) would appreciate it if you went to see them during their office hours to discuss minute details, rather than waste our lecture times. The professor or guest speaker or whoever only has one hour in the lecture. The rest of us want to learn. If you want to debate/discuss/elaborate on the finer points of ____, or put forward hypothetical situations to dis/prove a theory, do it on your time, not ours.Sometime after 11am is not an unreasonable hour to have a conversation, even in halls.
Yes, I know the walls in halls of residence are paper thin and you can practically hear the person next door's thoughts. But if I'm standing in the doorway of my friend's room and our conversation (at normal volume) goes on a bit longer than anticipated, at practically midday on a Saturday, we are not being unreasonable.
This happened in first year. It was going on midday, and party girl who doesn't care about disturbing people at all hours of the night because she's drunk, thought it was highly unreasonable that some of us would actually have a conversation in the daytime.
Cue her shouting, "It's 11 in the morning!" as if we were committing some heinous crime. Um, no. Just because you went partying all night, does not mean we should tiptoe around you in the daytime. Don't complain bitterly about the university not supporting/helping you at all, if you haven't even told them you're having problems.
Universities aren't psychic. And while they DO care, the reality is there are thousands of students here. They can't keep tabs on every single one. They might note whether you turned up for tutorials etc (if a register is taken), if you're handing in work, or failing classes; whether you've paid the rent on your room in halls of residence, etc. The flip side of all the freedom you get? It's taking responsibility for yourself. So if, say, your grandmother died and the grief is affecting your work, it's up to you
to speak to your tutor/lecturer/adviser, get yourself an appointment with the counselling service, etc. The help is there - you just have to ask for it, rather than expect it to fall in your lap.
