Lecturers at uni usually have bigger fish to fry, so teaching is not up to scratch at all, mostly death by powerpoint. You have to accept that lectures can and will be mostly **** and hopefully if you self-study (he says, procrastinating as we speak) you will rediscover some of your thrall.
The work is usually pretty banal too, in my language classes in particular all the topics are really boring. I find that when I'm doing the work that's been set I tend to go above and beyond if I'm interested, just on Wikipedia or whatever - give this a go. Remember that the set work is the bare minimum really. It's all about self-study.
