Again, these are a supplement to your own reading of the book. They would be an extremely poor substitute for reading the text itself. The laboratory exercise links will take you to a copy of the lab exercise. This is probably not useful to you at all.

The exam links will take you to some sample questions from previous exams. I am unlikely to use these exact questions on your exams, but they might guide you in studying for the real exams. I've outgrown that bad habit. You are much more likely to have an essay exam that may require diagrams and a lot more thinking, and maybe even creativity, on your part. Being assistant department chairman, though, makes my time unpredictable, however.
