I took this course on line and this is not the textbook to use. I just want to add that I ended up earning an A, I don't want anyone to think that I am blaming the book for a poor grade. A few of the chapters were very poorly written and the subject matter hard to follow. Some of the problems were so mixed up and time consuming that the time I spent digging out the pertinent information needed to solve the problem, could have been used to learn the material and acquire a better understanding of it as well.
Also the 11th Edition and the 12th edition is the same book, and thus many of the problems were the same except for the referenced dates. It is really a shame that colleges do not do their homework and give the student a break financially ($ 100.00 dollar difference or more.)There is no reason for them to demand the students to purchase a newer version when the older version would have sufficed.
I would strongly recommend to purchase the accompanying STUDENT GUIDE. This was not a requirement, but well worth the money. I will add that it did help me earn that A.
