I may not even go here, but well this goes for other universities as well, not just UoM
Sometimes I feel that I can get more out of going through the tute questions at home rather than at the tute, given that we're given solutions to the questions afterwards. Don't get me wrong, some tutes are great to go to, others I feel that there isn't much to be gained from actually going into the tute when we're just doing exactly the same as what we could do at home, and with the solutions there we can still get help without the need of the tutor (also considering that some of the tutors will just read off the solutions anyways). I think that might be because I'm better at independent learning though, so it's what works best for me most of the time.
This may come down to the fact that you guys are probably talking about tutes from different faculties? I see what Hancock is getting at, as I was mostly talking about engineering style tutorials. For your other areas and faculties it might be a lot different, a lot more valuable than what we're getting. Being able to take that time which I would have to go to the tute and move it somewhere else during the week can be valuable when there are other assessments that are due. It's more flexibility for the same result.
A lot of the time when we had participation marks for some eng tutes, most people would just do some incorrect working to get to a correct answer to show the tutor so that they could just get out of there and go home (was a later tute and some people had their last bus home leaving during the middle of the tute). As a result they wouldn't go and do it properly at home as they'd already spent time on it. whereas for the units that we didn't have participation marks in tutes they actually did do it properly at home, which was more beneficial than the other tute.
We're adults now, it's our choice whether we choose to attend or not, and for those tutes that I didn't go too as much I wouldn't give them a bad review, but rather not give the review at all (although I guess that's because I wasn't pissed off from not doing as well, could still do well in the end). Once we finish uni we're not going to have someone there pushing you to do this or to do that, you've got to make that decision yourself, and to an extend that has to start now if it hasn't already.
