I think you really must purchase the book, minimally. I wrote a post on one of these topics that explains about 50% of what you would need to know. I deliberately don't put into my posts more than that, because I feel that would be unfair to Scheele.
The book probably costs about $20 nowadays with shipping and handling and, maybe, tax.
Since you probably can't get the book in time for your test I suggest the following:
Try using your intuition to help you in this manner. Ask yourself:What kind of question is the teacher likely to put on the test with 90% probability? Whatever answer comes up for you, that's what you study. You might get alot of small questions and a number of probable essay questions. Hunt up the answers to all such questions and memorize them as best you can.
If you took notes during class, USE them! Experiments have shown that in 80% of the time, teachers use questions from their notes. Which means you'd get a B if you didn't do *any* other studying!!
Then go through your book another pass, setting the bar lower, so the question becomes:"What kind of questions will the teacher ask, with 80% probability?" Again, hunt up the answers and memorize.
If this is all you do, the odds are you will get between a B+ and an A on the test!
Good luck!
