I think I've just had a bad experience with the CSP system...my two are Beginners French, and Planetary Geology, both of which I have found incredibly dull.
The Beginners French teacher is patronising, its as if she doesn't want to be teaching the class to a bunch of people who can't speak French. A few weeks ago she pretty much told us we all sucked at French, which doesn't do much for the self-esteem.
Planetary Geology is just dull. The lecturer just reads off lecture slides that were probably made a very long time ago, and offers no extra input. He makes a potentially very interesting course very boring by not making an effort...he too looks like he'd rather be elsewhere than teaching the course.
Though I've heard good things about a few of them....one for musicians to go for is Orchestral Studies, because you'll be put into the Concert Band, and that's great fun to do for CSP. Heard good things about Web Design as well, and also a history one. The Language ones are ones to avoid...I've heard nothing but bad things about them, mostly due to quality of teaching.
Hope this helps!
