How good are Cram101 books, are they worth buying?

[malcs]

I just checked, and you can get the older version of the textbook for $1.88 from half.com.

Go to half.com, put the isbn number in the search box (0-534-63441-9), do the search, then click on the older editions tab. I alway get either an older edition or a foreign version, and never pay more than $25.

I NEVER read the whole book, just the chapter intros, summaries, and quizzes. What the correct book allows you to do is find an exact phrase that used on the practice or sample exams. Sources like Wikipedia, and others have too many viewpoints to find the exact description that you need for the test.
