I was lax about going to certain classes. Not always because of laziness (though, I'll admit it was occasionally a factor) but often because the format of one person, who lacked any particular talent for teaching, reading mostly from notes or scribbling incomprehensible symbology on a blackboard in a room filed with hundreds of people wasn't really a teaching format that did anything for me.

That's the thing though, in many places Europe people usually aren't paying much for university, and higher education is funded by the state. So the state has a keen financial interest on people not failing/doing over because they can't be bothered to go to lectures, a lot more than the students themselves.

The reality in my experience is that, whilst students are on paper adults (mostly) and responsible for their own successes and failures, a significant number benefits from being forced to attend. That's unfortunate for the ones that could "safely" skip the lectures and have to go, but on average it leads to better overall outcomes. So in that regard the attendance policies are sensible.

For NZ citizens to go to university it's only around $5k NZD per year and most degrees are only three years, except for a few which are four.

I only paid 50 bucks per month to study at university — there were many classes I never visited only wrote the exams
