Hope you're right!I do believe they end something like 10 minutes early so allow people to get to thier next class on time
bear in mind that lectures are very long, boring and tiring.That is correct.
At least for my mats1101 and phys1121 labs last year, we had to finish everything within 15 mins of official ending hour.
When I first started I felt the same way. Really, all the lecturers know about back to back classes and they always finish 5 min early to allow you to get to the next class. Then they always start 5 min later.does it matter if your labs, tuts and lectures are all back to back i.e no time to get anywhere in between, or do they not mind if u are a bit late?
