To be honest, if you can get great grades without going to lectures, and just by looking at books/lecture notes, you've got real talent. You're also doing it the hard way, and probably missing out a few nuggets of great info that the lecturers deliberately leave out of the course notes and know isn't in books to MAKE those with poor attendance get poor grades. Comments we've already had are totally correct, those along the lines of "advice over essays" ect, and bear in mind that they are the ones who will mark your coursework/exams, so it is prudent to learn how to do it all their way, and pick up any tips/methods they give you.
More to the point, what most people I talk to don't realise is that they have won places at the uni that other people would have killed for, and all to many people waste them by not showing up to lectures ect and failing. I know one guy who's been abroad on holiday for this whole semester and missed all the handin dates ect. I didn't get my first choice, which meant not going to a russel group uni, and I just know that there are a lot of people who beat me to get onto the course I wanted who have just wasted it by skyving off.
I guess all degrees are different and I'm sure there are degrees where lectures are total rubbish, so maybe I don't fully understand the situation. But I know talented people who skyve off lectures ect and bump along at a pass/2:2 rate by cramming when they absolutely deserve a first, a complete waste of talent, opportunity and the taxpayers money. To make it even worse, they all think they're doing great and even brag about it to weaker students, but it's really sad to see and I'm sure they'll all regret it. I know that I could do that and get away with it, but I go to all lectures and regularly get 100% in exams and courseworks, and am well in with the academics in the department. I will get great references (a point someone else has already made), which I wouldn't if I just skyved off.
In short, if the lectures are really that bad, then say that at this meeting. Chances are they'd LOVE to hear your feedback. But I really would recommend going to lectures ect, because you probably learn more than you think.
