This represents what I think is the most distilled form of this course. It's a little thin on illustration but, if you've done even a few of the labs, you should be able to use this information more efficiently than poring over the book, though the book is good for examples if you need more. Knowing the material here will prepare you for the tests/final and, if you don't just brain dump it the night before the test and instead pick it up as you go along, it will help you work through the labs.
