DON'T LISTEN TO THEM NINA, YOUR SITE HAS FLOURISHED AND YOU RECEIVE INFINITY HITS.
Can you ask the lecturers questions after the lecture? Like, physically go down to them to ask them stuff? Or are they always in a hurry to rush off?
Also, is it the lecturers who set the assignments and tests?
Are you allowed to email your lecturers to ask them questions, or can you only email the people who take your tutes?
There are usually a few people who crowd around the lecturer after the lecture (quantum mechanics lols). Many seem to prefer email, so I email unless there are no students asking questions (protists) or the lecturer has a 30 minute break between his lecturers and can't be bothered returning to his office, so he plays Muse at full volume during intermission (Schiesser).
Yes. Or coordinators.
Email seems to be the preferred communication unless otherwise specified. Lecturers will specify whether you should direct questions to tutors/forums (Mind, Brain and Behaviour, Critical Thinking With Data) and if they don't (Chemistry 1), emails are generally reciprocated by the lecturer within a couple of days.
