Peter-
As the author of these questions you've been passing along to comp.lang.scheme, I'd advise you not to worry too much about them. It's true I put them on the midterm and final exams in 1992, but as I'm now at MIT and no longer teaching at HKU, you probably won't encounter them on your exam. You'd do better to try and figure out what sorts of questions will be chosen by Andrew or Francis or T.H. or whoever's teaching CS202 this year.
If worst comes to worst, my last-ditch advice would be to sit down and actually learn the material.
I just can't get over what a convenient and powerful educational tool netnews is. It's certainly opened my eyes, anyway. -Olin
