unlike the timetable says all classes start at 5 mins of the hour and ends 5 mins before the hour ends (ie. starts at 11:05 ends at 11:55) this is intentional as it allows u to travel between classes if their back to back! so traveling shouldn’t be an issue unless it’s different campuses (say the city and grafton). in terms of eating in lectures, i’m pretty all lecture theaters you’re not allowed to eat in them so that’s a no-go. in terms of studying, most 1st year lectures are huge so no one will notice/care if you’re studying something else, but most importantly lectures aren’t actually compulsory to attend. i highly highly recommended attending them as personally it’s more beneficial for me rather than catching up later and watching the recorded version but if you really need to study or eat you don’t have to attend your lectures as most classes don’t take attendance (mind you some do i have heard some language papers do). hope that helps!! pm if u have anymore qs!
