You should double-check as to whether you are actually exempt from labs, then. If the content of labs has changed, enough since then, they might not allow it. They usually specify a time period in which you had to have taken the course to be exempt. I took it two years ago though, and I don't think it's changed THAT much, but it can't hurt to double-check. Also, you need a minimum mark in the labs (I think it's 80%, but I could be wrong...) to be exempt.
If you're really worried about the 3-4 questions on the labs, then spend the $5 on the lab manual
As far as course materials go, that's pretty cheap!
I remember our first two labs involved synthesizing, recrystallizing, and then breaking apart aspirin. The other three, I don't remember.
